The "fastest gun in the west" problem is really only an issue if you want an answer within one day of asking the question. Long term I haven't noticed it being a big deal. Over time, if a question is relevant, good lower ranked answers will rise to the top even if faster, lower quality answers were voted up initially.

The worst case scenario is a question which is perfectly written such that it garners attention from experienced folks who know what they're talking about for only a tiny amount of time, and ever after only garners attention (via google searches, for example) from clueless noobs who can't judge the quality of the answers (and don't have the rep. on the site to vote answers up or down anyway). However, this is a pretty contrived scenario which doesn't play out often in real life. Important questions will garner attention by people with a range of experience and qualifications, which will have the side effect of improving the quality of answers over time through future voting etc.
