I've already gotten one comment from a person who feels miffed that they're not on my blogroll.
While I was bouncing between aggregators over the last year (nntprss to Shrook 1.3 to Shrook 2.0a to Bloglines, where I rest now), I have admittedly lost some feeds here and there. Data loss does occur.
If you see an omission, don't take it personally. Just point it out to me and I'll do my best to fix it. Chances are I might be reading you on my LiveJournal friends list, or I may just not have you on the blogroll as I'm not sure about your real name.
