A sampling of 30% of average forum users isn't the same as 30% of the community, and certainly not the ecosystem. In reality individual users and organizations carry different weight. At the end of the day people who believe in Bitcoin (and invest their money into it) will do what they can to protect that value. The fork which has the most economic value will be the one most likely to survive with confidence of those who continue to accept it.

My understanding is a lot of heavily weighted entities in the ecosystem already support Gavin's proposed course. The larger challenge is for the minority to convince enough users - of all sorts, not just ideologues - to stand with them.

As it stands I think we already have, or can gain enough consensus to proceed with minimal discomfort. If there remains a market demand for 1MB blocks afterward it's certainly easy to have that. I don't understand the need to drag along those who want to ensure larger commerce adoption and market confidence. Cryptocurrencies don't operate in a vacuum, and they're not going away.

On a side note I also like Litecoin, another thing I was first to promote in the context of community growing pains.
