I now have 90 users, 44 communities, and 9 feeds on my list.
That's quite a lot of removals... 53 users, 27 communities and 8 feeds now gone.
One thing I did when working out who to remove, was check when their last journal entry was. Those of you with multiple journals (4, in one case), I have removed those that are no longer active.
Still, it means I can revise my filter now! :o)
Heh, and I've just noticed that makes a total of 143 users/communities/feeds on my friends, whereas before the cut it was 143 users only!!
Edit: I've also just noticed that I've removed a total of 88 accounts from my friends list - the same number as I used to have in my viewing filter!!! Freaky!
