I’d like to use tt-rss but I can’t self-host atm. I was wondering if there is a free public instance available somewhere. There is this old thread https://tt-rss.org/oldforum/viewtopic.php?t=2220 which name a few but all of them are either dead or closed for new registrations. There is http://readtiny.com/ but it doesn’t support SSL…
And it’s not free, but neither is bandwidth or electricity. US$1/month is not at all unreasonable – especially since they don’t have any ads on the site.
