What does the term "data smog" refer to?

Ways in which to 'beat the smog':

1) Turn off the television for at least an hour or two every evening.
2) Spend some time each week without your pager or cell phone.
3) Resist advertising – never buy a product based on unsolicited email (spam).
4) o on periodic "data fasts". A weekend in the country away from the telephone can rejuvenate a smogged-in brain.
5) Write clearly and succinctly. Verbose writing is wasteful and difficult to read.
6) Skim newsletters and magazines and rip out a copy of an article or two that you really want to read and digest.
7) Filter your email. Many email programs allow you to set "filters" which send unwanted email directly to the trash. It is worth taking the time to do this.
8) Do not forward chain letters, urban legends, urgent messages about email viruses, or claims that Bill Gates will send everyone thousands of dollars.

These things clog up everybody's inbox with worthless stuff.
Organize your Web bookmarks or Favorites. Keeping these in meaningful folders will go a long way toward helping you really find that site you are looking for.
