I'm doing this as a hobby/challenge. The blog: www.21pips.com
Yes I plan to write new articles weekly, however if I don't see an increase in traffic I might not have the motivation to continue.
I'm not an expert in SEO, but it seems impossible to me to get a decent SERP (even for long tail search) in this industry. I'm competing against huge banks or websites with crazy pageranks.
Thanks, that looks like a good way to find a profitable startup idea.
But here I'm just looking for a small side project idea, and I'd like to find it quickly. So taking random people to lunch seems a bit overkill.
