Just about to start a massive linkwheel campaign for my new site. After reading over everything on the subject, my gut still tells me that interlinking the properties is a huge mistake. Thats an obvious clue that Google will catch on too. If in the near future they decide to discredit linkwheel links, they will easily be able to discredit your entire network of Web 2.0 properties. Whats the point of interlinking them anyways? Just so they get spidered and indexed? I can get something indexed in 24 hours by simply throwing some social bookmarks at it. I honestly believe the cons outweigh the pros when it comes to interlinking. It just doesn't seem worth it to me... What do you guys think??
