Basically any personal project. lol
I use them all to test and increase my own skill set, and I take a very odd approach (much like the CEO of Netflix.) If it hasn't been done yet, and it's not "trendy" enough. possibly resulting in a loss since there's no proof that it will fail or succeed... I take it as a personal challenge to make it work.
My three "babies" right now are:
- A social website that makes you "earn" your membership by proving your ability to be a part of it. It will grow at a rate of one new user per week, voted in by existing members. I'm going for a concentrated business model for this one, with the attempt to see how valuable it would be to have the equivalent of Facebook - that doesn't let people join and interact simply because they want to. You need to earn it.
- A web site about video games, that is a creative community, which slowly reveals itself, through a gamified rewards system, as a web-based video game itself with a competitive nature to it.
- The "sister" of the previously mentioned website. As the user base grows, and people show favoritism towards a type of video game, it then groups them as either "A" or "B" - and at the end of each month, user stats define an ongoing storyline/battle between both sites. Also, as a user starts to shift from their interest in a type of video game through interaction (ex. from liking FPS/RPGs 40%/60% to 55%/45%) their site starts to visually merge and become the other site - applying their stats and loyalty to their new allegiance. ;)
