A WebmasterWorld member explains that there has been a 10% drop in the exchange rate from dollar to Euro as the US economy "deteriorates." He presents a chart of exchange rates that Google has used:
Jan: 0.771 (i.e. 1 dollar = 0.771 euro) Feb: 0.763 Mar: 0.748 Apr: 0.734 May: 0.740 Jun: 0.744 Jul: 0.723 Aug: 0.736 Sep: 0.708 Oct: 0.703 Nov: 0.675 Dec: 0.695
Most people are not particularly happy about this, unless they have to pay their developers in dollars, at which point the depreciation of the US dollar is actually a good thing.
But perhaps it's time to start looking at alternatives to dollars in earning potential:
Why not diversify? Try to earn part of your income in U.S. dollars--e.g., from AdSense--and the rest in euros, GBP, or another currency that's strong (at least for the time being). If your site has a global audience, you shouldn't need to tie your fortunes to a single currency.
Do you think that the US dollar will continue to plummet? If so, will you make any changes?
