This isn't a question of how, it's really more of a philosophical question. We get used to seeing certain avatars and associate users with them. It's kind of like a friendly face. So, the question is: do we keep our avatars forever, change them often, or try a few until we feel comfortable with one to keep forever?
Hey Royal. I know what you mean when you see an avatar it's like seeing their face, then wham they change it on you. I do like change thou for myself I sometimes get bored of my own face LOL
I expect that mine will change from time to time. I sort of like mine, but haven't yet found a better one on the way to the 'perfect' one. Even a 'perfect' one may change on a whim. Like hair color in my younger days, "subject to change without notice". (These days, that's too much trouble, so just letting it do its own thing.) Avatar may change, go back...hmmm, what do I want today?
I tend to like certain flowers a lot and when I photograph them I consider whether they would make a clear easy to read avatar. Once I get bored with that one, then on to next one. Just my 2 cents.
