I understand that people can seek status in every group. But that doesn't mean that talking about your career, in a status section that very few people bother to check, is the same as gloating.

If OP prefaced every comment with "by the way, I was the founder of such-and-such which was acquired" and then went on to discuss something completely different, THAT would be status seeking. Instead, it was a very short, objective summary of his career in perhaps a dozen words.

My point is simple: not everybody is status seeking all the time. Sometimes people are just trying to communicate with no ulterior motive.
