A couple things struck me immediately.
One. The top 4 sites are search engines. When people want to find something online, they go to a search engine. It only makes sense that the top sites would be search engines. On a side note, #’s 3 and 4, MSN and AOL should be thrown out as anyone who uses their ISP services is forced to use those sites as a homepage. Thus, each and every one of their users counts as a unique visitor. Kinda unfair if you ask me.
Two. Never underestimate usage’s ability to boost traffic. Ebay, Hotmail, MySpace are high user usage sites. It makes sense that they are this high. Side note here is that Google and Yahoo are not necessarily user usage sites as you don’t usually need to be a user of the site to use the main function.
Three. The ability of a site like Myspace, Wikipedia, Blogger and the like to rise from nowhere is amazing. Gives new meaning to the phrase “if you build it they will come.”
Where will these companies be on this list next year? Will Google overtake Yahoo? Will MSN? Or will a darkhorse come out of the shadows and overtake them all? Perhaps thatedeguy.com will be that darkhorse? Ok, maybe not.
