No, no. You don't get to drop design advice and then feign technical incompetence. That's "just saying" in another form.

When you say technical hurdles, I liken the process of getting this to work to be much like this (www.youtube.com) (Not Safe For Work. At all.). Actually, that's what I think of just about all Web 2.0. Maintaining the state of numerous widgets on the page gets very complicated. It may save time for users, but also makes things brittle, and hard to troubleshoot if things go wrong. I've had to build entire applications where each little piece on the screen had the potential to dial back to the server to request information, update contents, page through data, whatever... It was an absolute nightmare, and that was even using a fancy Javascript library that was supposed to take care of everything for me. That this is becoming the norm is somewhat irritating. Even for those that have solved the technical stuff (Facebook, Twitter), I still don't feel the potential for scrolling infinitely, even if you don't choose to, is good...

Hmm. I just had an idea.
