The avatars do matter but you should not get carried away by the picture displayed in the avatar. The avatars may some times be false. Do not believe it entirely before verifying the fact
It kinda tells who you are i think. I mean, everytime i see that weird cartoon robot in an avatar space, I know its one of cheap CEO services posts.
your own avatars make you unique to tell the truth I have mistaken who's who by looking at those with same advertising avatars (sold avatars)
Yes, it's very important and it looks better. It also shows more about your personality. Mine is a Rammstein avatar.
I'm new so I appreciate the question and all the answers. It seems the common theme of avatars are to show personality and as a site/logo promo. Still learning the online ways.
