A) You can just keep movin', movin', movin' such that dust cannot settle. This has the added benefit that moss cannot grow on your stuff.
B) Once every year, you can take the sleeve of the sweater you're wearing and thoroughly wipe the dust around until stuff looks nearly dust-free. This has the added benefit of, well, not much unless you count not having to send those really annoying little postcards into the USPS to have your mail forwarded.
I certainly know some people who tend to choose A. I, for worse or better, have apparently chosen B.
Also, my blogging skills leave much to be desired.
