I guess I forgot to mention that this job is with yet another startup. Though true, I'd probably be looking at a much narrower scope than running my own gig.
The team there is still small, but the guys at the helm have set up and sold their own companies before and have pretty good contacts and networks from what I hear (hence the opportunities for learning and gaining contacts). So unfortunately, it's not as clear cut as startup-vs-corporate life.
As for my startup, no offence, but I probably won't discuss it here… though hopefully we'll be able to announce something small soon =)
