I was looking at my Analytics a little bit ago, and I was noticing how much of my traffic comes from my social networks. In the last few weeks, it has surpassed direct traffic. Pretty cool if you ask me. I resisted Twitter for the longest time, but now that I have embraced it, it has benefited me emmensely. In fact, hopefully some of you that are reading this came here from Twitter. I could go on and on about Twitter, but I will save that for another post.
Flickr is another one that is driving LOTS of traffic. A few months ago I went back through a huge portion of my images on flickr and added a link to the site. For a little while it was the biggest source of traffic to the site.
