There is personal experience - from our people and the many that talk about hashtag successes. As examples, "operation wallstreet" rallied tremendous community support with #ows and then related hashtags like #owsboston etc. When there was media blackout about a rigged election in Iran and phonelines were even blocked, a hashtag spread the truth. What's more, it was my personal experience, during the big earthquake and tsunami (tidal wave) in Japan, and seeing how I could find very relevant tweets from hashtag streams rather than the cover-up on Fukushima on TV that led me to understand that hashtags have power - but that no one knew which was any better than another.
