It's a little better today. I had been using steemitstage.com, where devs test their new code, and it was okay until yesterday or the day before. This morning was horrible, I switched to busy.org but prefer this interface. Right now I'm back on steemit.com and it's been stable so far.

Also I really like the "Steemit More Info" browser plugin, which shows a bunch of additional info on profiles, vote tallies, etc.
