Edited to add: I decided to pay the small fee for the simpler domain name. It also gives me greater flexibility in futzing around with the site. Best of all, there shouldn’t be any ads popping up on you.
By the way, I haven’t paid anything to WordPress upon starting this blog. One of the ways it supports itself and provides a free blogging platform is by selling ad space on free blogs. At this time Nine of All Trades is a free blog. What I’d like to know is whether the ads you’re seeing are too intrusive. I suppose they might be so I’m taking an informal poll to consider if it is worth paying for.
I don’t seem to be seeing any ads when I look at the blog myself but that might be because I’m the contributor and admin.
