The popular Russian blogger Artemy Lebedev [1] is known for changing the title of his blog every few days. Usually it is a line from spam emails. The current title is the translation into Russian of "We now accept rubles (RUB)", most likely taken from the Wikipedia fundraising banners.
Lebedev also happens to be a designer who created the ruble symbol; it is not official yet, but used here and there.
