I have very long hyperlink that ends up getting broken at the '-' character in the About Me box. Also I believe it does this in the Comments area. I do like that you have made http:// come out as hyperlinks automatically, but when linking to a map like this, it will just end up confusing someone that comes across it and clicks on it. Also, a secondary annoyance about this is that these long hyperlinks don't word wrap inside the about me box, and "bleeds" through to the right hand margin and generally looks kind of bad.
long URLs like this can be problematic. You may want to try something like http://tinyurl.com/.
