Found this neat tool today, haven't seen it discussed on here yet (not my site, sadly). BUZZ SUMO: Code: http://buzzsumo.com You type in a domain or keyword and it finds the most-discussed and most-shared sites from the last 24 hours (or week or month etc). It's also pretty good for finding people on twitter to follow and see what niches have a small twitter presence (aka can be dominated easily). Use it to see what competitors are doing socially, or see what topics/article titles work. Great research tool if you use some creativity. aaaand it's free while in Beta mode.
