- Don't copy "about me" from my oldest account when I join a community
- Use another profile other than the oldest when joining new community or site
This is basically the feature-request version of the second link above.
Can we have our profiles synched from our Network Profile (or the site we've chosen to display as NP) instead of the oldest site profile?
Personally, my oldest site profile is SO, which I update frequently, and is usually not suitable on other sites. My NP, OTOH, is specifically written as
My profile on Meta Stack Exchange: <link to my MSE profile>
This is, IMO, suitable to be displayed on an arbitrary SE site as my "about me".
Problem is, now I have various old versions of my SO "about me" scattered around on individual sites I joined from time to time (usually for flagging spam - not relevant here). It'd be nice had they been the above "designated profile".
