I appreciate the public service and the knowledge gained using Wikipedia; thank you!

I use it all the time to gain basic knowledge about anything.   It is such an important resource for everybody.  

Wikipedia has empowered me for more than a decade to learn about anything and everything I could possibly think of. Knowledge should be shared!

Open culture and knowledge is one of the most precious gifts of the internet and we must fight to preserve it.

I gave because I value the free source and available resource that Wikipedia provides.
