Hello Friends
What is your view about using HTML5.
I thought it was too early to use it because it was new.
But heard that Google Wave was built as an HTML 5 app.
What do you think?
Am I rushing by starting using it?
Thanks

Lot of the old browser versions don't have them implemented; and lot of people still using them. I would not go for it personally.
