One of those things that can get really annoying after a few times, is clicking one of the searchresults in your favorite search-engine, which will navigate you to a site that then shows you that you need to signup. It happens to me everytime with Experts-Exhange.com. They manage to get their pages indexed by the Google crawler, so searching for some technical keywords will often result in links to Experts-Exchange. Most of the time I don't even look at the domain that a result comes from, I just look at the title and the compact piece of information in which my keywords were found. When I then happen to click a link of Experts-Exchange.com, I can read the problem-statement without problems, but then after scrolling a bit down to the answers of other forum-members, I see that all of that content has been scrambled to avoid me from reading that without paying a fee for the site... The first time that happened I was just impressed and laughed about it a little bit... but then when I keeps happening over-and-over again it gets quite annoying. Keeping the Dutch spirit alive (ons ben zunig) I refuse to signup for an account.

I thought at first that signing up was for free, but clicking the link shows the following prices:

Well.. it's easy to save money on this... I happened to try what happens when (in Google) I clicked the "In Cache" link and I must say I was kind-of surprised! It took me to the unscrambled version of the page!

Clicking that showed me exactly the same page as before with 1 difference: it's not scrambled anymore! Here's a screendump of the accepted answer (does not happen to contain the technical solution, but you can see the text is readable... so are all other posts).

My explanation for this "feature" :-) is that the Experts-Exchange page will not get scrambled when it detects the Googlebot crawler, as they want ALL TEXT to get indexed, so their posts will show up as search-results. That way, Google can easily index all content without any scrambling. When you as a regular visitor will go to that same page, scrambling gets enabled as you have a useragent that sounds like MSIE or Mozilla. This will probably work with many newspaper-sites as well who open up their articles for members only.
Anyway, I know now that whenever I click an Experts-Exchange link from the Google-results, I will go back and use the In Cache option to avoid the malformed contents on the next page. Maybe this happened to you as well, in that case you could take your advantage with this.

Sander had a great comment to this post which is worth while mentioning here. You could also add the Experts-exchange domain (with optional subdomain wildcard) to the list of restricted sites (assuming you're using Internet Explorer). This will cause the scramble script to be disabled, showing you all comments without any problems. Thanks Sander for the tip.

Unfortunately Sander's tip does not work any more. When you now visit Expert-Exchange, also all words in the comments are mixed up. So even when you look at the unscrambled text, you will still see meaningless words. So, using the Google Cache option now seems like the only way to read the comments successfully.

For several weeks now Expert's Exchange is "publicly" viewable. Indeed when you just scroll down the answers are there, readable just fine. In both MSIE7 and FF. So it seems this post became obsolete.
Day 1 of DevDays 2007 in Amsterdam RAI was a great success if you'd ask me. I have visited DevDays 2004 as well, and I remembered that I then found it very much like a big Microsoft commercial back then. This year however I really enjoyed the sessions by Scott Guthrie and Dino Esposito. I attended a lot of ASP.Net related sessions which really inspired me to add more Silverlight and AJAX components to my site(s). Also some information on when-and-how to apply LINQ was very interesting.
After this day I added some new bookmarks and RSS-feeds which may be worth viewing for you as well. Make sure that if you want to know more about Silverlight to view the posts on Scott Guthrie's blog on "Silverlight Airlines". That demo app. was really mind-blowing if you ask me. Now it's up to myself to create such rich user experiences. Somehow it always looks a lot easier when it's demonstrated... when trying to apply those tricks myself in my own applications, it always seems to be more difficult. :) As soon as some new Silverlight/AJAX page are live I will post it here so can give your honest opinion about it. Make sure to check out the following blogs to stay up-to-date about the most recent technologies:
Scott Guthrie's blog (check out his Silverlight postings)

A few days ago I downloaded the May-preview of Expression Blend 2. I wanted to have a look at the Silverlight-options it offers. I was surprised to see that this download took not more then 26 Mb. After I installed it I had a first look at the darkgrey, industrial-looking interface. Except for the use of the grey colours it reminded me about Macromedia Flash. I played around a bit with Macromedia Flash several years ago and I guess that for designers who have experience using Flash, Blend will be very easy to use. It's quite intuitive once you get used to the collapsing panels and the lack of rightmouse-context menu's.
After previewing this 30-day trial of Blend 2 I decided to get the full-version of the current Blend version as well to create my first Silverlight application. I should have known that Silverlight is not an available projecttype in "Blend 1", it only offers projecttypes "Standard application (.exe)" and "Control Library". So if you want to create Silverlight animations you should have a look at the trial of Blend 2. I must admit that I did not have any difficulties creating animations using the timeline, but adding interactivity is a hurdle I have to overcome in the next few days. I think it has something to do with limited functionality in the preview: the controls-pane does not show any button-controls, where the "regular" version of Blend has a much more extended assetlibrary (one of those assets is the button control).
Additional information:
My first creation is attached to this post (it's a WMV-file, wrapped in a ZIP-file and it should show you a web-banner animation). I will probably work on some other Blend-projects in the next weeks so I will post those creations (or links to them) if it all works out well. Any hints on creating Silverlight projects are welcome!
