Not weird at all.

Ever have a picture taken of you, alone or in a group, and you say "I'd like a copy of that?" Because you're in it you feel you deserve a form of partial ownership.

Same with messages. You are not the only participant. The person you message has at least the same amount of ownership invested in it. After all, they spent time, thought, and effort with their replies. And even moreso if the thread is on their Wall or Talk page.

It is also a matter of appreciating and respecting the contribution of thread participants. Attributing credit to their contributions is no less valid than you wanting any edits you do on articles to be accredited to you.
