I am planning to begin a garden blog with the primary purpose to track my before/after seasonal progress. This will be mostly for my own use, although I have no qualms about others following along. I plan to retire in September and begin my blog in October, hoping that my first year with no work obligations will result in a Magical Year of Gardening. We shall see...
Trux, you might join a regional forum and then begin a before/after thread within that - I can see that being a fun way to share results of hard work.
And, often folks will start a specific thread to a major project they are undertaking (building a new garden shed for example) with progress photos along the way.
Lots of ways to share. Poke around into forums that catch your interest. And welcome!
