I spent some time checking out Kinja yesterday too, and came to pretty much the same conclusions you did. By way of contrast, I have been using Jaeger, a new aggregator (and then some) developed by David Janes of BlogMatrix fame. Although it is still in beta, after only a week or so of using Jaeger, it has transformed and greatly enhanced the way I read weblogs--and other parts of the web as well. With it I can drag a link of a weblog (or a weblog entry) that I'm interested in into Jäger's window and the proggie takes care of the rest--even if the particular resource doesn't have a syndication feed. I can edit the view and change the way the weblogs appear in the "recently updated" list and "skip" items, entire weblogs, or categories. Skipped items disappear from the recently updated list, so when I go back to read later, i don't have to wade through items I have already read or decided I didn't want to look at. I can even get my Jaeger installation at work to sync with my Jaeger setup on my home computer. Remember some years back when it was in vogue to make fun of AOL users as totally clueless? Well Kinja seems like it was developed just for that sort of Internet user.
