This is where this and say Magic Submitter RULE. Use scrapebox to find thousands of sites with the footprint you are after (I think pligg is something like "Share and enjoy links and tags" or something like that) Anyway, you can then add tens of thousands of sites to your rotation.
My MS setup now has over 4,500 forums in 11 categories, So many blogs that I can't post to them in one night no matter how fast I set it (many thousands) RSS sites (9000 from a list on this forum) Video Sites (over 120) Press release sites (100+) and finally small ad sites. It works so well I'm back in the Ewhoring business with over 250 small ad sites.
I don't touch Craigslist! Lets face it with ghosting and deleting, account closing and counter spamming by CL staff, it really is a fecking waste of time unless you set up with hundreds of dollars of kit and are prepared to keep investing over and over again. My way is virtualy free. It's just something my tools do when I can't think of anything to write to promote my main sites.
Chloe and Angela are back on the street corner - red purses twirling in the breeze
(I owe it all to Diamond Dave the owner of BHW - whose book in this subject got me started some years ago - if you find it - get it, the basic stuff still works a treat)
Anyway - BMD and MS ... All in all these two combined can make you so many links you'll shit yourself.
But NOT straight out of the box. Spend a week/fortnight learning how to make these into UBER linkmakers and add thousands of sites to them.
'Course, if you do it wrong, you'll get sandboxed pretty darn quick!
Software that lets you adapt and grow is the best out there. Stuff that confines you to set methods or a few spammy sites to link from is not the way forward.
I'm talking to you SENuke!
