I really like RSS for the aggregation functionality. No need to visit many liked sites separately, only one where all the great new stuff is waiting in a list for me to filter. Big thumbs up to Tiny Tiny RSS for added filtering capability of RSS feeds.
I got annoyed of reading headlines that I’m really not interested in. Open source is awesome, because thanks to the openness many users use it, can hack it, fix it and so the features are better user oriented, shorter feedback loop.
When I discovered it I was determined to implement it if didn’t exists.
