"Hey you! This is me and this is what I have got!" "Hey back! This is me, and I like what you've got!" "Hey you! … Come join my community and we can talk"
There are plenty of web based community sites out there well worth exploring, and you should join more than one! This is because there is not just one single community web site out there that will reach everyone. Your best chances in exposure is to have your presence, music and community groups all happening in a few of them. Once you have done that then you can link them all up together to get the best coverage.
In all of these existing web based communities, the best potentials for maximum exposure take time. You have to build your name and community size.
The likes of Myspace in my opinion are good, and worth while having a presence in, but it will take time to get noticed in amongst the millions of other exposure seekers. It's a hard nut to crack. There are simply so many other people trying to expose themselves that you get lost in the wash of those who are already established, and it is difficult to get noticed.
The very best opportunities come when you can get into communities at the start. Be the first in. Get a great foot hold. Get your own name. Be active, and get the exposure that you are after.
You want attention, go to where you will be easily noticed!
