I have a fair amount of code that people can re-use to build their own aggregators, since I did a number of experiments when Google Reader died.<p>One was a Fever clone that had a number of strategies for doing parallel fetching:<p>- <a href="https:&#x2F;&#x2F;github.com&#x2F;rcarmo&#x2F;bottle-fever" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;rcarmo&#x2F;bottle-fever</a><p>Andrea Peltrin took that and evolved it into Coldsweat: <a href="https:&#x2F;&#x2F;github.com&#x2F;passiomatic&#x2F;coldsweat" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;passiomatic&#x2F;coldsweat</a> - which I recommend if you want a web UI.<p>I did a number of other things, but eventually went back to what I used _before_ Google Reader: e-mail.<p>I was one of the contributors for <a href="http:&#x2F;&#x2F;newspipe.sourceforge.net&#x2F;" rel="nofollow">http:&#x2F;&#x2F;newspipe.sourceforge.net&#x2F;</a>, and after getting bottle-fever going I decided to investigate the state of the art and did a quick fork of rss2email that injected messages into an IMAP store instead of sending them via SMTP, to avoid spam traps.<p>It was a quick hack, but it allowed me to read feeds using any mobile IMAP client, and a friend eventually did a Go version, which I&#x27;ve also tweaked to my liking:<p>- <a href="https:&#x2F;&#x2F;github.com&#x2F;rcarmo&#x2F;rss2imap" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;rcarmo&#x2F;rss2imap</a> (Python)
- <a href="https:&#x2F;&#x2F;github.com&#x2F;rcarmo&#x2F;go-rss2imap" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;rcarmo&#x2F;go-rss2imap</a> (Go)<p>Any of the above are likely to save people a fair amount of time (do bear in mind that the Python version was a hack atop code that was written by Aaron Swartz a decade ago, and it shows its age).<p>These days I ended up going back to Feedly, simply because I have to use Windows, the Web UI is good enough and there are lots of good clients for the platforms I use (NextGen, Reeder, etc.)<p>Plus I realised that trying to archive stuff from hundreds of feeds was somewhat pointless -- the stuff I really want to keep around goes into Pocket or OneNote, and that&#x27;s that.<p>Edit: Also, here are some notes from 2008 on Bayesian classification and its effectiveness: <a href="http:&#x2F;&#x2F;taoofmac.com&#x2F;space&#x2F;blog&#x2F;2008&#x2F;01&#x2F;27&#x2F;2203#an-update-on-my-rss-setup" rel="nofollow">http:&#x2F;&#x2F;taoofmac.com&#x2F;space&#x2F;blog&#x2F;2008&#x2F;01&#x2F;27&#x2F;2203#an-update-on-...</a>
