Why Free Plans Don’t Work
Great article over at Software by Rob on Why Free Plans Don't Work - well worth reading. What I took away from this is that for a free plan to be worth while the free users need to add something. If free users add to the community through content, examples (e.g. code snippets), network effect/validation etc. that the paid users can benefit from then they are a good thing. If, however, they are just getting a free ride because the free version meets their needs then you are potentially leaving money on the table.
