I would have guessed they were into fast sailing ships!
I've frequented other forums that had the same goofy-titles-based-on-post-count feature and I've never paid much attention to them. I think the original idea was that the titles for higher post counts should sound more 'prestigious' therefore encouraging people to post more often in order to 'level up'. That probably doesn't work if the titles are puns and it's not obvious what they mean or what order they go in. I think it's useful when one first joins a forum to be able to quickly identify who are the most frequent posters, but the post count does a clearer job of that than the title or the row of dots. I think if the feature bothers some people and nobody finds it particularly useful, it would be better if it quietly went away.
As for real names vs pseudonyms, personally I use my real name everywhere on the Internet but that's just my own preference and I will defend the right for others to use a pseudonym if they choose. Sometimes it's a matter of safety (avoiding stalkers) but I think a lot of people use them on forums to keep their personal lives separate from their professional (e.g. teachers may not want their students to find out what they get up to at the weekend). It's sad to say, but in some very male-dominated forums women sometimes feel they need to use a pseudonym in order to be taken seriously and avoid sexist/creepy behaviour (I hope this is not the case on c.net). Also bear in mind that just because a name sounds 'real' doesn't mean it couldn't also be a pseudonym.
