Euan has some very good stuff on his uneasy relationship with aggregators.
It felt like I wasn't really visiting people any more. I had turned relationships into content. I was also increasingly frustrated that I didn't really know who was reading my own blog as it is hard to get a sense of how many people access your content through RSS and because of the lack of referalls you can't get to know them.
EXACTLY!! I didn't quite know how to word that part of my frustration--but Euan has.
