I agree that some signatures may be annoying, but I'd encourage you to accept people for who they are - even for who they think themselves to be from their sigs. You meet a lot of people who value different things... the challenge is, can you show them something more valuable so they'd learn not to boast in little things?
On the flipside, sometimes a sig can come in handy when people are troubleshooting a problem, and your answers/advice coincide with specific hardware that they're interested in (for example, I have people asking about my MOTU 896 a lot - as for the 3 chords and the truth, well, no one seems to give a damn about that
