best way to start on angel list is:
1) get at least one notable angel to introduce it / submit it
2) ideally have them introduce you to a few others (privately)
3) once you have some visibility / traction with a few folks, then set your listing public and open it up to the rest (if you want)
this should probably be a separate thread here or on Quora to discuss best techniques for marketing a deal on Angel List. i'll try and write a blog post on this or a Quora question in the future. it's worth diving into more.
