I've waited for 2.2.1 to be realease (not quite this version number, but a bugfix for 2.2) before upgrading my 2.1 version. It seems to be working as it was expected, and those widgets support.. yes it's worth upgrading, but do not forget to backup existing blog as something may go wrond and you'll get nothing working.
wordpress.. 2.2.2 released.. I have updated .. to wordpress 2.2.2...
Wordpress functions were simply growing..
Wordpress 2.3.1 was realeased a week back..
It's such a popular system, but yet it seems to go on its knees the fastest when having been dealt the slashdot effect.
bloggers used wordpress..... really a clean and easy to use. and no installation hassels.
