I created an account and I consider shutting my own low traffic, personal homepage and blog. I think I belong to a sort of target demographic there. I also chose this to finally get a "start page" on the web with links to my social network profiles to find me. There are many others like it but they usually don't offer the same value and bonus feature sets at all.

That it's $20/year is very little but also significantly raising the likelihood it'll stay around for years. The author is also intelligently creating relatively low maintenance but high value services so this actually looks workable in the long term.
