I haven't yet heard what, if any, formal relationship AskPatents.com will have to the examination process going forward. However, at least for an already-issued patent a re-exam would be required.
Its like trolling backwards.
Absent some statutory changes, it's hard to see how it will impact the prescribed, formal steps of the patent review process. Patent filings are a lot more complicated [edit: as compared to existing legal forms websites], but I can imagine a template interface that would allow crowd-sourcing before a final review to cross the Ts and dot the Is.
It would be phenomenal if the PTO streamlined the process themselves. Baby steps...
