I've tested making a bunch of web 2.0 properties both directly linking to my money site and interlinking to each other. I have scrapebox backlinked some, bookmarked some, pinged some, or just left other's to sit. The results? Very little improvement in SERPs. The backlinks are being indexed and I'm getting about 20-50 links per day appearing in Webmaster Tools, and my anchor text is highly varied. All the content is spun, but highly different for each blog (a series of 10 different spun articles being used). I am using Ultimate Demon. I am primarily focusing on Wiki's, Web 2.0's, and bookmarks for my backlinks. I have tested 2 new websites and aged domain with similar results. Is anyone else having similar results with Web 2.0's and Wikis?
