I have a pet hate that is related to this and that is when people use one internet photo from 10 years ago that made them look great but isn't actually what they look like at all. Then you meet them IRL at a conference and it's... awkward.
I was talking about this to someone recently who called me a hypocrite because my [insert interface that I can't remember here] photo is one that was taken 5 or 6 years (and 2 or 3 hairstyles) ago. I had no idea, because you never see that picture.
So I guess my feeling is yes – it is helpful to be reminded of what you're putting out there for the world to see.
