Yes there are some sites that many people don't know about but yet they are huge. For instance-- http://www.craiglist.org Its a huge site, but you won't hear of that site a lot. About Alexa... Its owned by Amazon.com, and also powered by google.com All big names.. Alexa is one of the largest site of its kind. "The ranking from Alexa.com is not valid since this ranking is based on people who use the Alexa toolbar." but thats not true... Firts of all how can you say that its not valid when Alexa has been doing since 1996 and why would Amazon.com buy them?? According to Alexa.. "Site Stats Alexa gathers Site Stats from a variety of sources to provide key statistics about each site on the web. These include: Traffic Rank and Speed which are derived from Web usage information, and Other sites that link to this site, and Online Since, both of which come from Web content. For an example of Site Stats, see the Alexa Overview page for Schwab.com. " So ranking is not based on the toolbar that has to be downloaded.. Only the related links info is gathered from th etoolbar users. I m not going against sajha.com, but i was just trying to show you how others such as Alexa does the ranking. And its a pretty interesting site. and the popularity of sites doesn't depend on the sajha visitor. For example. like I said craiglist.org
