Ask HN: So I've learnt Ruby, now to choose where to go next?

So I've project managed high budget e-commerce builds across different platforms and languages, multiple smaller sites and am a pretty dab hand at SEO to boot, but having the funds to outsource and manage the project myself was just not a feasable option. So a few weeks ago I ordered a few RoR books and decided to get my hands dirty myself. I've found it a steep learning curve I must admit but it's definitely rewarding.

So to get to the point where should I go from here, essentially I am a solo founder and my location in the uk does not lend itself to finding a suitable co founder, there simply isn't a network and given my experience in a previous startup with poor co founders I know all too well how a bad choice can stick with you. I would love to bury my head down, get something out there and apply to the current YC application round but know the preference on team applications. So should I hold back on this round and try to find that elusive co founder or go for broke anyhow?.
