...this guy is full of shit.
I blog full time. I parent full time. I husband full time. I have to rein myself in, or I'll slap up a hundred posts a day, and confuse all of your pretty little heads.
Group blog all you want. Maybe two or three out there don't suck. Just remember, the only dual effort writings I can tolerate are when Stephen King and Peter Straub get together, and I still haven't finished 'Black House'.
I make a little money from this, and I'm grateful for it. I'd do it anyway, and you damn well know it. I'd like to think I stand out, but I am genuinely afraid of fame.
I am writing professionally, or rather for future professionality, and I have no idea if I will try to sell it, or not. I wish someone would set up a pay site where people like me could contribute their work, and get some renumeration and acclaim, and still stay relatively anonymous.
