I clicked a list named ISTORYA, and this is my Twitter feed for ISTORYA
1.) FOLLOWING : These are the list of people whom you included in the list.
ALL TWEETS of the people you followed/included in the list will be shown on the Twitter feed of the said listing.
2.) FOLLOWERS : These are the list of people who followed your list. They will be able to keep track of your list too.
IF YOU DON'T HAVE ANY LISTS YET, you may create one NOW!
This is a helpful tool so that you may keep track of the tweets by group.
Just click the LISTS tab and a drop-down menu will appear.
Click CREATE LIST
Search for the people you want to include in your listing.
BUT THERE'S AN EASIER WAY TO DO THAT 
Just go to your FOLLOWING tab (list of people you follow)
Beside FOLLOWING button, there is an ICON for the lists there.
When you click that a drop down will appear with the current LISTS you have.
Then, just check on the list of your desired listing for that particular person you are following.
Another is a LIST FOLLOWING YOU.
These are the lists where you are included/followed.
CHECK : You are following the list
PLUS : You are not yet following the list but if you want to follow the list, just click the button
There you go!
LIST DOWN ALL ISTORYANS in one LISTING.
In my case I have 116 istoryans listed in my @hinikkipee/istorya listing
and 12 are following my list
