I had a concept about something like this about a year ago. I mocked up some draft designs for a homepage and user profile. You can see them here (although the domain is expiring soon):<p><a href="http://sharemeup.com/sharemeup/index.php" rel="nofollow">http://sharemeup.com/sharemeup/index.php</a><p>Only the tour and index page have content.<p>Basically, my concept was socializing and in essence, noobifying the stock trading process. You buy shares based on dollar amount (fractional ownership, ShareBuilder.com does it as well). Ticker symbols are accompanied by company logos, so its obvious that you're buying Apple Computer stock, not just AAPL. Your portfolio is also gamified; win achievements for doing well, get placed on a leaderboard, share with friends, etc.<p>In general, everything about trading is complicated. If you look up your favorite company, and you're overloaded with stock information about High/Low, Bid/Ask, Volume, closing price, etc. And the more investment options are given, the worse it gets (mutual funds, options, currency, etc.). Everything appears complicated, so yes, it is intimidating. To get a better grip of what a better UI would be, it would be a good idea to look at the intentions and desires of a new trader. I think the average joe wants to start trading because: a) They think they're smarter than the average person, and can make a few bucks off their stock picks. b) They think it'll be fun to learn.<p>Feel free to take any of my work or ideas.
