So I set up TT-RSS the other day and it's generally nice, the only problem is I'm trying to find feeds that are interesting more or less. For example, we all enjoy watching TV, right? So I took the TV OPML from awesome-rss-feeds on GH and applied it, and was not amused. I don't watch that many television and I very quickly realized that none of the content in those feeds applies to me at all, so I removed it.
Don't forget that TT-RSS can filter articles for you. Say, for example, that your TV feed had a sci-fi category, and you only wanted to see that. TT-RSS can mark everything else as read (or deleted) so you only see that.
Useful for 'firehose' type feeds where you are only interested in a specific subject.
