Completely agree. I love theoldreader.com, and it's compatible with apps like Reeder. I used to host tt-rss, but I don't want to continually patch and update anymore.
Same here. Does what I need it to do, but I've noticed that it only syncs one-way with NetNewsWire (pulls feeds in, but won't update read status), unfortunately. It's still good enough for my needs as I'm not subbed to that many feeds.
