What are Twitter Lists and Why Don’t you Have Them Yet?
Twitter is currently beta testing LISTS. It is a way for you to be able to separate your time lines by sorting out people you follow. So you could make lists for:
- Friends
- News
- Sports
- Shopping
- Family
Only a small group of Twitter users have lists right now and during the beta testing, the lists are actually going away for people that have already made lists. I hope when they come back Twitter will have saved all of the lists becasue it is time consuming to make up.
Once you have lists you can also see what other Twitter users have lists and then you can also copy or follow their whole lists with one click. That is pretty convenient. 
Soon everyone will have them, so don’t worry just be patient.
Want to know if you are on a list?
Type this in to your toolbar but replace “yournamehere” with your twitter name.
