I wrote a little post a few weeks ago about an avatar drawing attention. I switched my avatar to a a little green monster sticking out his tongue and I can officially say it worked. My community has added 40% more members since changing . Believe it or not I do have limits and passed on the avatar below due to the controversy and image problem it would cause. Putting a hot girl no longer draws attention because nobody believes a pretty girl is actually the user anymore and 20% of them seemed to have been switched to a cute girl. For this strategy to work it has to be truly different and eye catching , and my little monster still works. On days I feel sexy I may still use the one below.
