side note on twitter, even id you don't tweet anything, follow your local news, deal sites, etc.
I am a bargain hunter, and follow techbargains, techdealdigger, amazondeals, livehotdeals, woot. I find awesome prices on stuff all the time.
I also follow a few TV shows, tech news sites, etc.. Ill add them, and if they don't post anything useful, I drop them, or just ignore them, yet stay following them just to show my support (castle and chuck)
