You may have noticed that the urls in some feeds have changed recently. There are now a number of values that can be part of a URL query string that can customize a feed request. If you like, you can ignore these, but if you feel like fooling around, the values that can be part of a feed url are:
author: posts by x
ex: http://hubski.com/feed?id=mk&author=BorgoPo
shareby: posts shared by x
ex: http://hubski.com/tag?id=economics&shareby=Kaius
voteby: comments voted by x
ex: http://hubski.com/globalchat?id=mk&voteby=mk
type: image, text, video, audio, or magnet posts
ex: http://hubski.com/global?id=&type=image
replied: posts that x replied to
ex: http://hubski.com/comments?id=Owl&replied=eightbitsamurai
shares: posts with x shares
ex: http://hubski.com/tag?id=economics&shares=6
over: posts with more than x shares
ex: http://hubski.com/tag?id=feminism&over=4
under: posts with less than x shares
ex: http://hubski.com/posts?id=flagamuffin&under=3
time: sorted by time, as opposed to activity
ex: http://hubski.com/tag?id=poetry&time=t
These can be stacked. For example: http://hubski.com/tag?id=poetry&author=lil&shareby=mk
It's likely that this functionality will be further integrated into the site. However, we thought it would be interesting to get some feedback, and see what you all might be interested in doing with it.
