I think that's a perfectly valid opinion. Badges can be seen as a way to gamify social media platforms, and some people find that to be off-putting. Others may feel that badges are meaningless or that they don't add anything to the platform.
I personally don't mind badges, but I can see why some people might find them lame. It really depends on your personal preferences.
Here are some of the reasons why badges might be considered lame:
They can be seen as a way to collect virtual trophies, which some people find to be pointless.
They can be used to show off, which can be seen as obnoxious.
They can be used to manipulate people, such as by giving badges to people who follow you or who like your posts.
Of course, there are also some people who enjoy badges. They can be a way to show off your achievements, or they can simply be a fun way to interact with the platform.
Ultimately, whether or not you think badges are lame is a matter of personal preference. There is no right or wrong answer.
