The significant difference between MBAMap.com and the other web site readers out there is that MBAMap.com provides one with the ability to create a simple Blog of your own. Blogger, what I use, is fine too but it takes quite a bit of work to make changes and the learning curve is pretty big to customize it the way one wants. I'm still learning. In short, MBAMap.com Blog is really worth looking at.
Some other services that MBA applicants will really like are: 1) Business News - A web page of newspaper articles and PR/AP Wire news related to the business world and MBA's.
2) Top Business school News - Media News related to the following top Business schools: Harvard, Wharton, Stanford, Chicago and Kellogg.
3) MBA Program Info - A concise web page that contains crucial MBA applicant info of each of the top MBA Schools.
