After the notorious shutdown of Google Reader I hoped to just resurrect my old Gregarius deployment and was forced to face the projects death; so, what are you using instead nowadays? (Or, are you using any RSS/Atom reader at all?)
Not the author, but if you want to host your own you should consider goread (https://github.com/mjibson/goread) or ttrss (http://tt-rss.org/redmine/projects/tt-rss/wiki). Goread.io is the hosted version of goread if you don't mind paying the $3 per month. Otherwise you have feedly, newsblur, theoldreader, ..., but goread is really the closest to Google Reader (clean/fast UI, keyboard shortcuts are the reason I pay).
After much consideration, after using Lilina and then Gregarius with the Lilina theme when Lilina itself could not handle the number of inbound feeds anymore, I'm inclined to choose tt-rss... But I have not migrated yet.
Oh, I want to thank you for Gregarius. I still use it to this day and haven't found any replacement I like so far (tiny tiny rss just did not cut it last time I checked, a year ago).
I didn't really decide to halt development, the project simply lost momentum over time, I didn't consider it dead until a couple years later. During that timeframe I also stopped writing PHP and picked up saner web development habits.
Can't blame you. I have to admit I thought several times to modify a few things that bother me (e.g. to have a mobile-friendly version), but just the thought it's PHP pushed me away ...
