In one of my favorite movies, Office Space, Tom Smykowski (one of the fired employees) has a magic-eight-ball-style novelty product idea: a “Jump to Conclusions” mat. Sometimes, I watch discussions in the software freedom community and think that, as a community, we're all jumping around on one of these mats.
I find that people are most likely to do this when something seems
novel and exciting. I don't really blame anyone for doing it; I do it
myself when I have discovered an exciting thing that's new to me, even
if it's well known by others. But, often, this new thing is actually
rather mundane, and it's better to check in with the existing knowledge
about the idea before “jumping” to any conclusions. In
other words, the best square on the mat for us to land on is the one
that reads: Think again!
