To Old for Myspace?

Due to a high number of friends asking to "glance at my MYSPACE page," I--a thirtyish, left-handed woman--have been forced and urged to create a page. Okay...okay, maybe not forced but my hand was slightly twisted. Now, let it be known , I have nothing against Myspace. It's just I can remember when the darn thing was created and it seemed...well, it seemed like a place for junior high and high school babes. Even now, when you look at everyone "tagging" sites, it reminds me of my crew signing my high school yearbook. Yet the pages I've visited are pretty much the domain of bonafide "grown folk" or people in their thirties. So what does this mean? Is Myspace becoming a haven for adults who want to entertain the kid within or is it becoming a legitimate extension of glorified e-mail? I haven't even touched the issue of all the sales pitches...everyone is a singer now. What do you think?
