Current version of the Profile Pic (PP) I use everywhere was taken about 9-10 years ago. I was going to keynote at Broadcast Asia and they need a recent shot of me, so dashed out of the house to take this.
That's the problem with it - it's of a more youthful me. It would, of course, be wonderful if that many years hadn't passed and I was still fresh(ish) faced, but that's not reality.
That accepted - What to do? Shock people into the current realities of my now-matured faced?
I suspect many people are in the same position of their PP being of a far more youthful self - and in the same way of holding on to a rising balloon (or in this case, perhaps sagging) - every week that goes by, letting go becomes harder.
How about this? - A service that takes your youthful PP and your far more honest, this-is-what-I-look-like-now PP, and carries our some Tweening. This series of images would then automatically gradually be updated to your various profiles over six month, bring your public likeness nearly up to date - thus avoiding the shock for your followers of you suddenly ageing overnight.
