This is a post left on Backlinkfuels service thread. Seems like free Web 2 sites are not working anymore according to them...anyone experiencing this? "There has been another major update to the Google algorithm this month. Typically they spend the first week of the month rebuilding the index with the latest algorithm tweaks, and this one was another bomb, similar to Farmer. The free web 2.0 properties got their links almost totally discounted. I think this is why the U-nets are no longer working. We got a U-net in early February. It worked for us until this update, which killed its linking effects completely. We used this on an interior page of a site that has something like 500,000 links in total, so it can't be said that you have to use this method with other linking methods in order for it to work. This method is balanced by tens of thousands of other links on that particular page. I think the emphasis of this update was on killing off the free Web 2.0 properties. The links that are still working for us are the ones from costly semi-private networks like SEO Link Vine, Linkvana, and other truly private linking networks. Some of these have been added to the Fusion Package, but at a very high cost. I'd like to try Fusion, but I have been waiting for some reviews. I still think fusion puts too much reliance on free web 2.0 properties, and not enough emphasis, considering the high price, on the private networks. It never hurts to spread the links across multiple properties for natural look and feel, but I think the free web 2.0 networks are deader than a door nail. George is a smart guy, and I am hoping the coming new packages work as well as the old stuff did. I am a little gun shy because of of the massive changes going on with Google. Please consider what I have said in your new thinking."
