Hi,
there is an effort to add RSS/Atom feeds of participant blogs to Planet[1]. (idea by User:Legoktm)
There is a ticket[2] about it on Phabricator and i was bold and added Outreachy tags. And there is a Gerrit change[3] that i merged that adds some of the feeds i could find of Round 15 participants. I would be happy to merge additional changes if there are more participant feeds that you can find. https is really really preferred over http by the way. Unfortunately for some https is broken and an effort could be made to contact blog owners to fix https, maybe using Letsencrypt. Also happy to give hints how to do that. Cheers, ~~~~
