The 2, or 5 day average values are higher then ever. Keep mining and keep searching for ways to make your bitcoins useful in every day trading of goods and services.
That's a very good point: search for ways to make BTC useful (ie. trade for good and services). So far we have seen one place where it really makes sense to use BTC, and where traditional credit card based facilities fail: Silk Road. Without BTCs being useful for real good and services there is very little to support the current BTC/USD exchange rate. The rarity of BTCs doesn't matter to anyone who does not need them.
