I’ve been getting into the PHP/MySQL combo and am really enjoying it. I created this thing that is kind of a twitter for stocks. The idea being that if you buy or sell a stock then you probably have a good reason, so why not post it? It then does interesting things like finds which stocks have more buys and sells and it takes key words from people’s posts and uses them as tags so you can see that people who, for example, bought Apple (AAPL) tend to list “iPhone” as a reason for their purchase.
It is not yet fully functional; all posts are, at the moment, anonymous. So there’s no logging in or following other people, etc. etc. That’s a possible future addition for sure.
