For everyone 1 new webmaster that starts in this industry there is probably 100 new people surfing porn... More big link lists will pop up and people submitting quality free sites and galleries will still get listed.
I just started submitting TGP galleries a couple weeks ago, so im new (in that area at least
). And already i've had a few of them email me partner accounts without even having to ask. It's in the owners best interest to keep the good submitters around, no matter how new they are.
TGP's and link lists will fail without good submitters, and submitters will fail without good TGP's and link lists.
