Community news sharing site Digg has been acquired by Betaworks, Digg CEO Matt Williams announced today in a company blog post. Ordinarily, this would be a good thing, especially since the company has been making a serious attempt to sell itself for the last six months or so. However, the Wall Street Journal is reporting that the sale price was a measly $500,000 — ridiculously lower than the rumored $200-$300 million it was asking back in 2008.
