Having been an officer of the same guild since before World of Warcraft (multiple game guild), I have really no idea what you are on about. Find a mature guild if that is what your looking for, but do realize that most people there will be as boring as me

People in the setup I am in are promoted to an officer position based on what value they can bring to the guild:
raid leader (like myself) need to know the ins and outs of raiding and keep raiders happy;
recruitment officer(s) need to have a very good idea of what type of people will fit in the guild, and have very good people skills
guild master, the manager that need to give some direction for the guild and make sure the officers do their job
Then you can also get some officers just to sort out day to day problems in the guild, banking officers taking care of the guild vault, etc.
All of the above does not imply that you need to be in the guild for longer than another person, but you need to have the right skills for the job.
The type of guilds you find by people randomly inviting you and promoting you to an officer just so that you can recruit some more people randomly just is not my style...
Having had your own guild of 150+ members and leaving them or the guild disbanding with you does not bode well for your officer skills?
