Now, I could be making this all up–but I’m pretty sure that company closed down, but the developers resurfaced at oddpost, who did a great web-based email client, but, again: IE/Win only. (oddpost is, of course, now Yahoo Mail’s interface.)
Well, I’m a late to the party. (That’s okay, before the party there was a lot of pain. I’d rather be a little late than early.) But it’s a great party, and there’s certainly a lot of enthusiasm and momentum in this space.
At any rate–I’ve done work with scriptaculous and prototype in the past year, and am just starting with JQuery. As a technologist, you have to pick and choose what you are going to learn. There’s just too much out there to learn everything.
Well, I’m going to work on learning JQuery.
