Remember the video version of seesmic, the one that spawned.the francofous?
Things changed for two reasons. Bandwidth issues and ressources. Flash would suck down the laptop battery within a few minutes. It meant that you could.only Seesmic from a fixed position.
With html5 that problem will dissapear. What I look forward to is an HTML 5 optimized version. It could result in a greater number of users on less powerful machines.
I hope we see a growth in users and a more international set of users. I hope they also add more features at the same time.
Let us see whether Seesmic take advantage of this opportunity.
