I also subscribe to newsblur. If I ever decide to run my own instance, though, I'm sure that I'll be missing content. Many blogs these only include the N most recent articles in their RSD feed. So if you only start now, you'll be missing the older ones. Is there a non-time-travel solution to this?
Yep, liferea has the functionality of tt-rss and other hosted readers. It's not completely bug free, but you can fix them. Not sure why you'd go for a hosted one unless you really wanted mobile reading or something.
