This is, of course, a most excellent question.
The answer, my friend....
The most difficult thing about starting a blog is the pressure to keep it up to date. Its mere existence is enough to require content. And, like everything web - a dead blog is a sad thing to see. Even if no one ever looks at it.
To make matters worse, there is either a tendency to try to be 'oh so clever.' Something I can fail quite readily at. What am I waiting for?
We're going to try a trial blog for the next two months to see if this is a worthy component for our farm and CSA. At the very least, it could become a feedback area for our farm share members.
