Probably. My thinking is that the low CTR (click through rate) can be explained by poor targeting, but once you arrive to the landing page you should have a pretty good indication of whether you want to trial or not. The low number of conversions to trial just from reddit is a bit strange.

That said: any ideas for better subs to target? /r/sysadmin, /r/linux were some of the smaller ones i'd considered, or i could go wide with /r/technology, but this experiment has left me feeling cautious.
