I have been on a serious hiatus lately from both blogging and blog reading, and frankly it's great. It's high time for me to re-think my blogging habits and my subs. This comment from Chris Coulter on Scoble's blog nailed it - just don't start!!
I also can't find the reference right now, but Bill de hÓra had a very cool GTD-like suggestion awhile back around organizing subs into daily/weekly/monthly reading folders. I seriously need to do that.
