Also, I like "Support Wikipedia" better than
"Donate to Wikipedia". I
think that the word "donation" has the wrong connotation, more
"Disaster-relief" and less "Non-profit foundation"
I prefer "donate". Giving money to a non-profit is a donation, so
"donate" is the correct word. "Support" can be in all kinds of forms,
for example signing a petition is a way of supporting a cause, no
money or anything else with monetary value changes hands. A donation
is a form of support, certainly, but if we're talking about donations,
why not say "donate"?
