I've always been afraid to move my feeds off of LJ/DW and into a dedicated reader, for so many reasons. I like the little bit of effort it takes to read a feed in DW, having to find or create it first; that's a natural curtail of potential feed addiction. Plus, I keep a pretty tight hold on my DW circle, so before I add a feed I think about it a long time, like I would before adding a personal journal or a comm. And because a lot of my feeds are not really easy reading (lots of anti-opression blogs) it's nice to have them mixed in with stuff that doesn't fill me with rage/sadness, but then when I get really busy in RL I can choose to view only personal journals so that I can keep up with the people I care about and skip the feeds for a while. (But since they are always part of my reading list by default, I never entirely fall out of the habit of reading them, which is a bit of a danger for me -- I used to read Twitter, but then I switched browser versions, didn't install the Twitter extension, and never went back.)

So, uh, that's my feed reading logic.
