It seems like every week or so Bitcoin moves further into the mainstream.

Most recently, it was online gambling. In November, even WordPress started taking payment in the digital currency. Last year, a Bitcoin bank was launched.

And on Thursday, the Internet Archive announced that it wants to collect donations, in Bitcoin, so that it can pay some employees, at their request—part of their salary, if they so choose—in Bitcoin. The online archive's mission is to store digital documents, including, most notably, previous versions of webpages.

If all goes well, wrote Internet Archive founder Brewster Kahle, the move will start in April 2013. “We hope to make it a continuing option," he added.

The group's address is: 17gN64BPHtxi4mEM3qWrxdwhieUvRq8R2r.

Kahle wrote the day before that Bitcoin is the “local currency” of the Internet.

“There are local currencies like Ithaca Hours or Bernal Bucks that facilitate trading within a community. Bitcoins are kind of like that. It is for those of the Internet,” he wrote. “I found getting it going was an adventure which ended in my figuring out how to donate to the Internet Archive, which was fun. People have donated over $5,000 worth of bitcoins in the last 2 years to the Internet Archive.”

Disclosure: Cyrus Farivar and Ars contributor Tim Lee both own some bitcoins.
