Will using CSS to hide in-line text for screen-readers affect SEO?

[viskar]

There's one practice I really enjoy because it's great for accessibility and for people who use screen reader, but I was wondering if Google could consider this ''an attempt to fool him'' and blacklist me for this? Here's my example : When I create a logo that is the name of the company, I really enjoy do this :\[code\]<h1> <a href="http://stackoverflow.com/questions/13778993/index.php"> <img src="http://stackoverflow.com/questions/13778993/my_cool_logo.png" alt="Coolness Inc Logo" /> COOLNESS INC </a></h1>\[/code\]And then, I'd do \[code\]text-indent: -9999px;\[/code\] in my CSS to push the text out of the screen, but people with screen reader would be able to read it... what do you think? Bad or good practice and could I be blacklisted for this?
