I find the site slightly slow, but nothing worrying.
On the other hand, the Follows - no matter how many times I click on "Old Follows", it reverts to the "New Follows" about a minute later.
Any ideas on how I should glue the Old Follows?
There is no "reverting" or "gluing". The old follows has a different URL than the new follows.
New follows: http://vatoto.com/myfollows
Old follows: http://vatoto.com/follows_comics
Just bookmark the old follows link and use the bookmark.
As for my thoughts on the update: I love it. The new theme is great and aside from the initial slowness, it's all pretty speedy. And I finally got Follows RSS!! \o/
