Default --data-format usernames is misleading for a tool called InstaComments

[trangtinkers]

The tool is called InstaComments but by default it only exports usernames, not the actual comments. That's pretty surprising for a first-time user.

Two things worth considering:

• Change the default --data-format to detailed so you get comments out of the box

Right now you have to know to pass --data-format detailed to get what the tool's name implies, which is a bit awkward.

Simple fix would be changing the default in the argument parser:

# before
parser.add_argument("--data-format", choices=["usernames", "detailed"], default="usernames", ...)

# after
parser.add_argument("--data-format", choices=["usernames", "detailed"], default="detailed", ...)

Otherwise, great work! Thanks for sharing.
