I disagree. I've seen them on a few other sites. The usual suspects welcome the new guy to the site, and that's it. I find that, if you post in the forums fairly regularly, you'll get noticed, you'll get private messages, and you'll make friends.
Would anybody read it? Since I have the proper medium though:
Hiya RealJock! I'm Chris. Been a member for a bit now actually, but I'm just starting to get active. Friend is taking some pictures for me next week so I should have some better stuff up to show progress soon.
I've been browsing the threads to try and get some smarter ideas on how to approach my workout, chatting up people who seem interesting, and abusing the Hotlist feature to no end. I really should stop hotlisting people, but a large ratio of this site seems to fit into my type.
Yep, that is what the about me section is for, mostly, but this is going on the premise that PEOPLE ACTUALLY READ! And considering the attention span of some, unless it is some half naked guy or a video game, the likelihood of the profile being read is nil.
Join in on the discussions and people will click through to your profile if they want to find out more about you.
As for not reading profiles, I read everyone's profile. If I'm going to click on someone's profile and they took the effort to write one then I'm reading it. Besides I like to see how everyone else describes themselves, but maybe that's just me.
I think the best way to introduce yourself is to start a topic on this main forum introducing yourself. It gets read, then, by many.
If there was a section for 'introduce yourself' it may just sit there with little interest. That said, it's worth the experiment. Why not ask admin about it? They're pretty receptive to creating new forums.
