Ah, tt-rss... After Google announced that Google Reader was going the way of the dodo, I spun up my own instance of tt-rss, and used their (paid) Android app too... until I decided to file some bugs on their Redmine bug tracker.
There were a few bugs I had encountered (can't recall if it was on the mobile app, or on the browser UI), and decided to report to them. I opened a few reports (maybe 2 or 3?), and continued on my merry way. Checked in a not long after, and discovered that the developer didn't bother to really read my bug reports, and instead, berated me (if my fuzzy recollection is to be believed, something to the effect of "I don't know what you're talking about" and "you're stupid go away"), followed by closing the bug reports. No effort on his side to try to understand, no further digging for more information if something was unclear.
Being a software developer myself, I'd like to think I'm generally familiar with reporting reasonably useful bugs (repro steps, observed behavior, expected behavior, etc.), and even if I didn't include all information, I'm more than happy to provide more as requested/directed. But being effectively ignored and then berated for trying to help? Ridiculous.
tt-rss worked okay for my needs (lacked polish), but still, no software is perfect, so if I were to continue using tt-rss, I'd undoubtedly run into other bugs. Going by my experience with abrasive/abusive behavior of the developer (I saw similar examples in other bugs in the tracker at the time), I decided to jump ship on the first sign of a reasonable alternative. Thankfully, Feedly came along, and I hopped on for the ride.
After Google Reader, I tried a bunch of different ones. Feedly was the best I could find but there were a number of things that just annoyed me. I had an issue with one of my feeds and got very little help from their support.
That was the last straw and I decided to revisit alternatives. I somehow stumbled upon BazQux, and I noticed the same issue with the one feed on that platform as well. The developer was incredibly helpful in pointing out an issue with the way I was generating the feed. That level of support instantly had me hooked (along with how much it functioned like Google Reader). I bought a life time subscription then and there.
One of the best parts is the ability to add any FB, Instagram, Twitter users as a feed. BazQux automatically converts the user's feed into RSS and serves it up.
No more having to go to FB for updates from various organizations that don't have any other mechanism for publishing announcements! :)
Yes, I had a similar experience with the maintainer when trying to contribute back to tt-rss (two pull requests closed with rather rude explanations that suggested my submissions had barely been glanced at).
Still, tt-rss offers killer features for me that other options don't: self-hostable, being able to write my own scraper plugins (the big one in this discussion), and a solid Android app. So I continue to use it and just keep any code improvements to myself.
