I like changing my picture periodically. Sometimes public events motivate me (death of Nelson Mandela, or COVID-19). And sometimes I just get tired of my picture.

I suppose as we acquire new images we like better, it's nice to update them once in a while. Every few weeks seems a bit often, but perhaps that's a cue into the member's personality, they like change. Those same folks are probably always rearranging their furniture and decorating their homes for various holidays. I have no problem with that.

This is me. You folks would recognize me in a dark alley

I think I do it because I think the icon should actually look like how the person looks at the current time.

I’m a visually oriented person so I like easy recognition of the person I’m responding to, but I guess some people may be more verbally oriented, so they pay more attention to names, or maybe some people don’t even care who they’re responding to - I don’t know. I appreciate people who leave the same photo up so I can instantly recognize them, or at least use a consistent style of photo, like donotbelieve does, even though she regularly updates it. Maybe that’s the best compromise.

People like to change things it's normal

It's like putting on a new outfit or expressing a mood. I like to change mine to fit an occasion or when I'm feeling a certain way. We also have names attached to our profile pic, we can only change that one time. We are recognizable by our names.

I've been a member for over a year, but initially landed here for the dating aspect, which I think most will agree is not this site's strong suit. I stepped into some bear traps while trying to find my way the first time here, (trolls, angry debaters, hookup hunters and romance scammers) but came to really enjoy some corners of the community aspect, as it does contain an increased level of enlightened, respectful, engaging conversation compared to most other social media sites. I left for a while but recently came back for the community ,and while updating some of my profile info, decided to change my profile icon. For me, it maybe was more about a fresh start and perhaps at the same time minimizing the chance of some previous undesirables making the connection. I figured anyone in the community I'd connected with previously on a relevant level would make the connection pretty quickly based on my name.
That being said, I see those who change their profile pic for messaging reasons as @Allamanda mentioned (I am more inclined to do this on fb where my 'friends' are largely people I know in real life and my real name is used) and I also think there is a group of people who do it out of vanity simply to ensure they get seen. On a site like this, where many people have never met in the physical world, I agree there's definite benefit to consistency when trying to connect posts and comments.

Likely the same ‘whatever reason’ folks do the same on facebook. I’ve wondered if there’s a problem with being too consistent..

Beats me why people keep changing their photos...it seems pointless to me.
