I think you need to have some help when making a bandwagon.
For example
Small concise messages can be bandwagonified by the concept of "what a twweeist"
You can fall back on "your opinion of me" or "post here and i'll give you my honest opinion of you" which can spin off to the former bandwagon the next day.
You can also attempt to make spamfic, but we've had two good ones recently so you'll just get shat on.
There is also the possibility of making a bandwagon by posting a member's name and putting the message in the body post in hopes they do the same.
Making an entirely new bandwagon is very difficult to break into.
Maybe a "I miss X from guildfall" bandwagon could begin if some makes "what do you not miss from guildfall?" thread to support the wheels. I've been thinking about that type of bandwagon for a while now because right now we're just cooler embers waiting for you to rekindle us.
Go forth and wagons
