I don't really have the money to buy a computer that will take a lot of work to get into the top 20. I'm trying to focus on other things right now. Maybe down the line when I have a little more disposable income I can invest in one, if for no reason other than network security. :)
I think a lot of witnesses post a status update every week. That just let's people know how things are going and what they've been working on. Check out @dragosroua for ideas if you want. He's one that I like.
