Oh, I have so much to say, and I really don't have time. I'll take two minutes ..

  MindQuilt is a private Q&A platform that leverages
  matchmaking and gaming dynamics to get your questions
  answered and documented FAST!

Don't care about "leveraging" or "matchmaking" or "gaming dynamics" (whatever they are) - I'd lose this sentence completely

  Have you ever spent an inordinate amount of time trying
  to find an answer a colleague could have provided in 15secs?

Can you ask that question in half as many words?

  MindQuilt connects the questions in your organisation with
  its experts and documents the results delivering Just in time
  documentation!

"Just In Time" is not a good buzzword to use. What you're claiming is that it automatically sends questions to the right person, and documents the answers for future reference.

What I'd also like (I haven't read further) is that if the same question gets asked in the future the system spits back the answer without having to trouble the same people over and over again. We have a system that does that - how does your system do it?

  Like Quora or StackOverflow for the Enterprise, ...

What are they?

  ... MindQuilt provides consumer ease of use while respecting
  the confidentiality and security required for corporate use.
  Where else can you post a question about internal products or
  policies?

What?

  MindQuilt reduces the cost of new employee onboarding by
  allowing your organization to build a knowledgebase of
  commonly asked questions, allowing your employees to leverage
  previous questions or to be connected to an internal expert
  immediately.

Oh, so many buzzwords.

OK, I'm a technical person and this is way too high on the Ginger factor. Make it more real, make it more direct, make it 1/3 the length, and make my pain your focus.

That's your two minutes. I'll look at your beta when I have time.

PS: All my own opinions - and I'm weird.

PPS: An email address in your HN profile would be nice.
