I like the latest version a lot. I always liked the old version best, with its rotating tweaks like sickles and such, but this is the next best version I have seen. The partial figure gets the superhero, determined gardener aspect, and the distressed typewriter font has a low-tech, homespun feel as well as linking back to the long-time logo. The whole figure with tree and plants was never a logo but an illustration, not readily translatable to multiple scales as a logo needs to be.
It also occurs to me that the typewriter font suggests individuals communicating (on a forum), which may have been one of the parts of what made it a good logo for Permies.com.
