Don't be surprised to see "Black Friday" or Black Friday products as trending topics all day on Twitter tomorrow and the rest of the weekend.
Retailers and consumers both will be using Twitter as a valuable tool all weekend. Retailers are looking to reach out and spread information to customers, and consumers will be sharing information about product availability, and crowds and traffic situations all day long.
Many stores will be opening at 4 and 5am, so look for Twitter to start buzzing early. Twitter activity should be extremely high in big cities as more and more people make the day after Thanksgiving a shopping tradition for great deals and a chance to secure that hot item before it may be out of stock.
Tomorrow should be a real test for Twitter, and used in the right capacity it should help many a crazed shopper.
