I made my first money on the internet in 2008, and life has never been the same. Hopefully I can pass on some of the things I've learned along the way.
I've been adding to my list of ideas for a decade. Some were great (they got built!) some are dumb (they got built and sucked!). Some are really dumb (I didn't bother). I add to it frequently, and occasionally I go through and "garden" it by grouping...
I made a very tiny tool called Spyyyder that grabs a page, tells me what links are on that page, and then allows me to drill down through each of them. For getting to grips with how a site is put together, it's a pretty useful tool.

I was recently asked for a recommendation on a Workforce Management System, with some requirements that were heavily focused on optimal staffing levels.
