Hashonomy is an interesting website that lets you figure out related hashtags. For example, here's the hashonomy page for thanksgiving. RElated tags #lovethepie #thebigcheese and #turkeytweet - I'm not quite sure why #bookshakalaka is related but OK.
Finding it interesting that the New York Times is taking thanksgiving questions on the hashtag - you have to tweet @nytimesdining with the hashtag #ThanksgivingQs - what an interesting thing. Why not try it?
So, if you want to use Twitter to find black friend deals follow both #blackfriday and #blackfridayalert .
