I've been sitting at my keyboard hammering away looking for ideas to write about. I came up empty too. It's not so much "writer's block" as a topical disinterest which engulfs me and bids me to just drop it.
However, this still falls in the classic definition of "writer's block" which is in essence being unable to think of what to write or how to proceed with writing.
So ... yet another blog entry goes undone in actuality even though the words exist.
