Sure it would be great IF all browsers supported it. I can't remember the point that I was trying to make when I made that post, but I think it was that the new things are great, but when FF is ahead of the crowd, it doesn't really matter when they add something so huge and fancy, because until the majority or at the very least IE supports it, it's less likely you will ever see websites that are coded with it.
A website coded specifically for FF is pretty rare if it all. I mean, websites are coded for proper CSS which FF seems to run the best, but for a whole new feature that (as far as I know or remember) only FF supports currently, we won't see anything until the announcement that it's included in IE too.
Like you say, there are small projects here and there that use the new tech, but for the most part, it's business as usual.
Perhaps those small projects can make benefits of these improvements, but then they should promote them to the developer side, and not make such a big deal about them to the general public where they don't much at all.
I just get sick of FF making a big deal about every release, when in reality not all that much is being improved for the most part.
FF is really getting to the point where Winamp was many years ago.
It does what it needs to do, but the programmers feel they need to keep adding on to it and making it do more than what it was originally designed to do.
I never wanted my winamp to do visual things, or tie into itunes, or make calls to the internet to find the names of my songs, but they load it up with all these crap features.
The addon idea is great, but now I want some plug-outs where I can say I don't need this feature, or this feature, or this feature, and unchecking those boxes or whatnot actually speeds up my FF.
Don't get me wrong, speed improvement for certain types of code is great and all, but don't make it like it's this huge improvement when:
1. It's not.
2. It mainly only matters to developers.
If it speeds up java in general, great. But speeding up java alone and making a huge deal about it is just absurd.
Speed up your browser launch in Windows 7. It takes 10 seconds to launch in that OS as compared to others. (MS at work here?)
They would do better to focus on addons having functionality across FF versions? I'm really tired of upgrading FF and 20+ of my addons stop working.
