I am not really lacking ideas but I just want to ask people what kind of scripts are they going to buy? I'm looking to use my knowledge of php to help others and earn money (of course). Note that I am also creating a blogging script so any thoughts about that one (things I might have forgotten to add) would also be helpful! Thanks.
I have heard people complain that wordpress uses 16 queries for every page load and that it loads up servers too much. If you solve this it would be good.
Wordpress is a great script that would be hard to out-do. Perhaps you would want to write some plugins for word-press?
