Let's be fair, the Wikimedia Foundation does many other worthwhile things besides keeping the English Wikipedia running. By way of example their latest full-project, Wikidata, was only started in 2012 and is already getting more edits than Wikipedia.

Thanks, good to know! This year's will be my last donation to Wikipedia.

Realized the same thing about a year ago about SPLC (splc.org). Once I realized how much cash they have I saw that my contributions would have more effect elsewhere. I like what splc does: help discriminate which groups are hate groups and which aren't, among others. But they simply don't need any more money IMO.

It's my understanding that by donating a small, but recurring amount such as $1/month, you are still helping organizations like SPLC or PP by adding to the numbers of their contributing supporters. That seems like a good alternative to cutting off support, which would free up the money for a more cash-strapped cause.
