I'm invisible, who knew?

Ever feel invisible? I remember being a dorky kid in the corner with glasses and braces and desperately wanting to be invisible, but I wasn't. Sure I was ignored a lot of the time, and sometimes thought I was invisible, I wasn't.
Nearly six months into my job people still don't know I work here. Nobody recognizes my name, or bothers to deal with me directly -- even if I've spoken to them.
This is understandable at a large paper with lots of reporters, but I find it strange and slightly insulting that nobody knows, or seems to really care that I'm here.
