On finding a cofounder: what is the likelihood that people will like your idea AND your proposed implementation technologies?

I don't know of what use it is to guess the "likelihood" of something such as this.

The way it works with us is I usually make the technical decisions with my tech partner in my mind. Yes there are times we run into disagreements but they are discussed and resolved UNLESS you make disagreements a personal thing in which case you might as well part ways with your team.

I think theres plenty of people out there who want to be part of a startup, but hav no idea whatsoever, or have just vague/pipe dream ideas about starting a company.

Right now I just need a really good flash developer, and maybe another super tech if they could contribute alot. I haven't been able to find one yet, but still have a few leads..

I think it is dangerous to expect a cofounder to be a yes-man. You are probably better off without a cofounder at all. I'd imagine a good partner would complement your ability, and provide interpretation from a different angle.

There are many different ways to build a web app and this can present a significant hurdle to finding cofounders. After all, some may like your idea but hate your choice of implementation technologies.
