Have a look at the sidebar of gBlog. It’s such a bad use of Flash. Sure, it looks neat with the rollovers, the “+ show more” and the tiny scrollbars, but it’s oh so stupid.
What do you do when presented with a list of links that all look interesting? You cmd-click (or whatever you do in Windows) them to open each one in its own tab or in a new window. Try. Didn’t work? Well, no surprise really, because the whole sidebar is a Flash application, which doesn’t work that way. So now you have to click the links, one by one, and each one will take you from the original site.
You open the links in tabs, you can’t copy the links and what’s more, the links are not visible to Google, there is no graceful degradation here.
I find that really, really stupid. Pity, because it’s not a bad blog otherwise.
