Looks like even Facebook can’t maintain a non-stop record of growth. Over the past six months, they’ve lost almost 2 million users in the US, as well as an unquantified decline in Europe.

This news has hurt the share prices of both Facebook itself (0.6% decrease) and Zynga (a more noticeable 5.2% decrease).

shares of Facebook (FB) have struggled of late. After reaching the low $30s per share at the end of June, the stock today traded at $27 before closing down a half a percent at $28.09.

When you take a step back though, with a market penetration estimated at or above 50% for many of countries it operates in, you have to wonder if it’s really feasible to continue growing – and with a claimed userbase of 900 million, maybe losing 2 million isn’t the end of the world.
