I think another question with the same answer is "Is this a good place to ask and answer questions about silver or gold or other popular commodities?" The answer is "somewhat". Commodities have a small but limited role in personal finance. They are more suitable as a general money topic. A few questions here and there discussing how commodities like gold and silver relate to money and investment vehicles suitable for individuals are clearly appropriate. BitCoin questions should probably be treated similarly.
BitCoin is mildly controversial. (Heck, investment strategies using gold and silver and other commodities can be controversial too). StackExchange is not Wikipedia but a modicum of Wikipedia's "neutral point of view" technique is helpful here: document the controversy, but try not to feed the controversy. Discussion of the issues which people find controversial about BitCoin is appropriate; extensive debate about it really isn't.
In-depth questions on how to use BitCoin are probably completely off-topic. I generally approve of the BitCoin StackExchange proposal to create a more appropriate venue for these conversations. If and when this BitCoin stackexchange is created, it may be appropriate to move more BitCoin-related questions there as a matter of convenience, even questions which might otherwise be on topic here.
