I was reading from my phone and after reading the first point he made the screen went dark and I couldn't pitch/zoom out to find the X so I just closed the tab... Would love to read it if it weren't so spammy.
Take today/tonight to make a game plan. Identify companies on that list that you like, map them, and go out and talk to them. If you're "in the area" it's really easy to pickup a few coffee meetings and eventually one of them will lead to something bigger.
When you meet with them be completely up front about your situation in the US, but DO NOT dwell on why the last job offer failed. Talk about their company/products/space- show that you've done your homework. That should lead to discussions on your passions/experience and if you've researched them and they have a position open, great! If not it's perfectly ok to ask them about other companies looking for someone with your talents.
Can we assume that Mozilla's software development is more technical than Wikimedia's software development? I think the only thing they have in common is that they're both non-profits.
Why would you want to apply for that many startups, simultaneously? Seems to me like they would all be working with wildly different technology solving wildly different problems...
I don't know about you, but I want people excited working with me.
