Nah, I have plenty now, thanks.

@avonweather (obviously my weather station account; muted by youngest daughter, followed by eldest)
@TheMorrisGarage (my personal account, which both daughters follow)
@AvonGardenClub (which I occasionally post to for my Twitter-averse wife)
@avon_f1fan (separate account so as not to clog my personal one, and to avoid seeing results before watching on DVR)
@StevenKMorris (unused, but there if I need it for anything before another of me snags it)
Plus three unused but there if I need them accounts on app.net - "the next Twitter"
