I would like to pull personal views of all users?  I wrote powershell but its pulling only shared/public views. So how to retrieve personal views of all users.

This looks like one area that a Site Collection Admin, server admin, User Policy Super user/auditor and PowerShell scripter cannot get data through the browser or the API. The only solution I have seen is a direct query against the databases. (A support no-no!)

If you are working in a non-production test/dev environment, then take a look at this project for some ideas: http://sppvimport.codeplex.com/ Click the Source Code tab and drill down to "SPExportPersonalView.cs" to find an example of the SQL.

Not being able to get this though the API is a bit annoying :-) so I'll look into it some more.
