What is to stop non-Bitcoin100 members from voting?
None! I personally feel that non supporters of Bitcoin100 have a vital roll in this issue, for what results out of there directly, and indirectly, effects Bitcoin as a whole.
What is to stop non-Bitcoin100 members from voting?
nothing. They can vote if they want. Maybe they will join the bitcoin100 after voting?Exactly! Moreover, not a single Bitcoiner shall ever called out is choosing to not supporting Bitcoin100.
First point is valid.
2nd point...what?
Allow me to clarify that 2nd point. Over at the Bitcoin100 thread, there have been posts by users currently not supporters of Bitcoin100. Their questions and concerns are important to not only Bitcoin100 but, moreover, Bitcoin as a whole. A member of this forum, who doesn't post very often, may log in one day, read, make a very important comment, and leave, not returning back to Bitcoin Talk for a couple weeks. We can't simply ignore their post because they're not a supporter unless, that is, they're related to BitcoinPorn.
I hope that makes sense, as well. I'm trying to articulate what's going on inside my head and, at the same time, address this issue with the utmost care.
