Out of the top 66 tags (#music - #apple), there are 11282 submitted posts as of me typing this comment. 5639 of those posts are contained within the top 10 tags (#music - #history). It's scary how close to 50% that works out to be. Hint: It's 49.98%.

I wanted to put some values behind what flagamuffin was talking about with monochromatic tagging, because I completely agree with his point. I think right now it's very easy to find people that you want to follow, the community page is laid out great. But I don't think as many people utilize the tags page, I know I don't use it to it's fullest extent. It could also be an issue where people want their posts to be seen and cared about, and thus only submit to tags that are popular which then fuels the cycle. If you're new to the site and want to gain followers so more people your contributions, then you can't really go about posting to rarely used tags. I love having the opportunity to post to a never before used tag such as #charm and know that somebody will see, but new people aren't afforded that as easily.
