This blog uses WordPress 1.5x
I was looking forward to upgrading to 2.0x which should allow easier posting of video clips and other important improvements.
Unfortunately 2.0, so far, seems to be a bit of a disaster.
Reasons to not upgrade to WordPress 2.0 from 1.5.2
Oops, perhaps I blogged too soon. Seems WordPress 2.0.2 is already out and I will attempt the upgrade … soonish. WordPress called it a “Security Update” but several bugfixes were of more value to me.
NOTE – I finally did update. No major problems. The new widgets feature won me over.

Hi there –
Thanks for linking to my ariticle! WordPress 2.0 was a bit of a disaster, but fortunately since then they’ve come out with WordPress 2.0.2, which is great (except for the wysiwyg editor — still need to disable it as it’s a nightmare).
So it is now safe to go ahead and upgrade after all. In fact, my blog is currently powered by WP 2.0.2 now 🙂
Best,
Emily
