Blogger uses the term label for what is normally called a tag. Either way I intend to use them in a specific manner.
I will use at least one of the following tags in each of my posts.
Economics - Financial Intermediaries, Cooperative Associations
Government - More on legislation than politics.
Food - Ingredients, Restaurants, Recipes, et cetera.
Hockey - Mostly NHL and New Jersey Devils
Football - American Football (mostly the NFL and Miami Dolphins); Also FIFA style Association Football or Futbol (mostly MLS and New Jersey Red Bulls)
Software - Libre Licensed Software, Computer Science, Programing
Off-Topic - Everything else
