Your "sources" are quora discussions that requires login w/ Facebook/etc. No thanks. It's a bit of a wasted post here. No one without a quora account can join your discussion, and the link-bait title just pushes a lot of folks away. I have to think that, if you actually wanted discussion, you would've listed more of your own thoughts. You only listed two that I see: "I would say no." and "Probably not."
Personally I have joined a startup and it depends what actually you want from your job. I mean if you want to be financially strong job then joining start might not be a good idea but if you want your growth and enhance knowledge there is no better option than start-ups. Start-ups sometimes also turn in to huge money if they investors or fund raising.
