If anyone is looking for their next idea, check out WordPress plugins

• validated demand
• tens of thousands of installs per any crappy plugin that seems remotely decent to get the job done
• tons of tiny plugins you can develop quickly and put into one suite for a monthly fee
• free traffic from WP plugin directory
• tons of exact match domains available

Just because competition exists, doesn't mean you can't take a chunk of it ;) if you only want a life lifestyle business to support yourself, it's not a bad place to start.
