Recently, I made a very small donation to Wikipedia. Wikipedia is an under-appreciated wickedly awesome creation - created by people who are working for barely (or no) money. The need for encyclopedias has dissolved, not because of various internet sources but because of one destination for largely trustworthy data.
I urge the millions who read my blog to make a small donation to this foundation.
Hopefully this link works some years from now...
All of should support this fantastic, free service that (I believe) has no advertisement revenues... don't tarry, send it some money right now. Please.
