I just wanted to share with you something, you are all missing a BIG TRICK. How many of you are taking full advantage of your profile? This is a cost free way to promote your products, not only is it free but you naturally get users that are already interested in what you have to say check you out. So why not use it a free platform to sell. This exposure can result in MORE SALES - I have personally put this to use and have with my limited profiles gained LOTS of business.
This applies to your avatar as well - It's another opportunity to gain exposure.
