I didn't know about narly.us.
The new design of repos.io will be a lot more intuitive. And faster too, i'm working on optimizations.
Btw, thanks for the link !
Perhaps we can help one another? Through narly is in ruby and repos.io is in python. In any case would be great to collaborate. My code is also fully available : https://github.com/plusjade/narly
Do you have any experience with redis or backbone.js ? I think backbone.js is supercool (play with the narly tagging ui if you can) but it does have a non-trivial learning curve and a lot of closure/reference gotchas that I struggled with. Anything I can do, just let me know!
I love redis, use it a lot on other projects, and it's used on repos.io but not for main storage (postgres and solr).
I don't know ruby and backbone (and really i can't read ruby !)
repos.io is cool because it offers a lot more like notes and followers.
narly.us just has the ability to tag repos but its backed by redis and Backbone.js so it's quite fast and (hopefully) intuitive.
I took some inspiration from antirez's post a while back: http://news.ycombinator.com/item?id=2338351
