Path has been the center of both a lot of praise and disappointment - it's focus on 50 friends or less is very unique. Instead of following people in Path, you "share" with people. That makes it very private and intimate - if that appeals to you, you will love Path. Their recent app update included comments, so now you can have great social aspects. However, you can't put filters on your images, and you can't share photos to Facebook and Twitter - it's truly an experience only for your closest friends. Unique feature - in addition to taking a pic, you can optionally share a short video.
