Top ten software development companies

Hi there,
Does anyone know about that kind of rating? I would mind taking a look.

If there was a list of such companies, one could rank them by Alexa rating.

For example,

alexa.com/siteinfo/microsoft.com

I think the top companies change every quarter, even though the changes are not major.
In my opinion nearshore is better than offshore if you have to choose between the two.
