1. Trending Tags - If something is liked and talked about it is easier to find. There are some great tags that lead you to amazing things. Try Vintage or Poetry.
2. Easy - It is really easy to use, only 1 page you have to mess with and it's not confusing.
3. Visually Pleasing - It is a great visual site with lots of great pictures and it's really fun and quick to look at.
I highly recommend Tumblr. Follow Me on Tumblr: http://www.tumblr.com/blog/buffaloonabudget
