One good reason is that you'll be doing the world a favor. This network works by means of crowdsourcing music intelligence. It doesn't work like your average site, presenting pages that sit there statically. It allows the creation of pathways, which are tacit recommendations and which guide people to artists and music (or to anybody on the network). Nobody has to take this advice; one decides based either on what one knows about the page owner, or on what gleans from what's on the page, whether it's worth taking or not.
As it is there are brilliant musicians on here. But in crowdsourcing, the more intelligence the better. Bottom line, we hope to find yours on here. And if you are a musician maybe some music too (anybody may create a page and pathways, although the content of the page must revolve around music)!
So do the world a favor! Thank you!
Oh, and HOW does it work? You sign up (no charge, and your information is not sold), and once logged in you'll see Create a Path to This Page on members' codex pages and elsewhere associated with their names. You click and confirm, and you will have created a pathway from your page to theirs, which will appear as a link on your Pathways Out tab (you will likewise appear on their Inbound pathways tab). You can unPath as well. Others can of course create pathways to you.
