Do you think users really cares about a html and css validated website

[techu]

well my index page gets validated but forumdisplay and showthread was showing more than 50 errors.
While correcting this errors I found that most of it was caused due to plugins.

And I also discovered that official tweet button and google buzz buttons were also causing problems.
So I edited the plugins templates to solve the error, but I decided not to remove  tweet button and google buzz.
