People who highlight these traits might be making excuses for being slow to respond because they are busy with other activities or interacting with many people at the same time. This often leads to poor experiences.
To those who write "I'm shy at first, but I talk a lot once I'm comfortable," I'd like to say that an adult highlighting their shyness in their profile is essentially showcasing their lack of social and communication skills. Not realizing how this comes across is quite embarrassing.
As for those who write "I don't really know how to use this app," you should have researched how to use it before starting (sarcasm) haha.
