The first thing I look for, if I chance upon a new forum while surfing, is signs of intelligent life.
Ask yourself this: What gets you hooked? To extend the fishing analogy: What's the bait that sets the hook - for you? You ought to be able to write any number of articles examining what interests you. Write some articles then open the forum with thought provoking questions or commentary - inviting replies, or you could simply do your creative writing as posts in your forum and invite replies.
I'm a big fan of helpful insights expressed with brevity and humor. There are tons of sites that fill page after page with fluff and anecdote, 80 sentences to make 1 point, often of little surprise or value. I'm certain there's people with time for that type of reading. Not me.
Maybe when I get down to site creation I'll have to adopt a dual personality: Homespun and robust. The problem is it usually takes me 3 days - of vacation - to achieve the laid back state ;-) So I guess I'll do my laid back writing whilst I'm on vacation.
Which may be a good excuse for taking more vacations.
But, if I'm working on vacation is it really a vacation, or can I take the expenses as a business expense?
Ack! As you can see. I'm not yet on vacation for 3 days.
