Next time you’re tapping out 2 single-spaced pages to Aunt Gertrude describing photosynthesis in all its glory and splendor, consider emailing it to something like Posterous instead; then, fire Aunt Gertrude a link to the page. Now, not only will Trudy have all the chlorophyll-related knowledge her blue-hair-laden head can tolerate, but Google will probably stop by and maybe send some other interested parties your way. And the next time somebody hits you up about it, you need only send them a link to that thing you already wrote instead of rehashing the same crap all over again!

Great advice from Brett! I have started to use GMail canned responses for some stuff, but I love the idea of the "personal FAQ."
