http://www.unrabble.com looks good. Liked the way you are allowing profile import from LinkedIn/Facebook. Wonder why you don't allow importing data from word resume.
I agree with checklist. This list is perfect for most startups but launch quick is not good enough. We need to launch and need to get good feedback so we can fix those issues. Sometime it is hard to get feedback. In that case we need someone who can market our product or who has good contacts to get the word out. Technical people like me has hard time to sell the product or idea. So for me (14) Hire or find co-founder with marketing skills.
Well my English has grammatical mistakes but it seems like my idea doesn't have that much issue. Yammer has announced my idea ( point 2 ) today... lets see whether it came from Hacker News Posting or it came from their brain :) We will see when Yammer releases that ...
Well that could be it. But still i think - if idea is adding more value to current industry then there is a scope. But I am not PG ( not yet ;) ) so, my thinking doesn't count ( counts for me - not for others ).
I am Ruby learner. The way ruby works with DB is problem for novice. If programmer don't do careful coding for caching then it is bound to cause problem. Ruby hype is all around auto code generation and simple coding/scripting. But when you are writing enterprise level apps then there is more to consider.
You generally mention that "ideas are less valuable than they think" but still I believe that to become successful - you have to have good idea. If you have bad idea but still founders are dedicated then over the time they could change that idea and they could become successful but thats longer process ( changing idea on the way is going to take long time to release the product compare to starting with right idea..) and sometime timing is also very important ...
Answer for this question is different based on location. If you are in US then degree is not that important as there are many people in US at higher post - based on knowledge rather than degree but if you are in country like India then degree matters because you won't even get chance for interview without good degree..
I have been thinking about same area for quite a while and not able to convince myself because there are many different sites with some partial information. And startup market has not large user base..
larger market <= more user and some day that returns more money compare to site with less user base.... well thats my thinking..
