Some might say the PML are the defenders of the standard quo.
Some might say the PML are opposed to all SPIRITed change.
Some might say the PML is a bunch of idiotic gossiping schoolchildren who cannot begin to fathom the utter serious condition of TDWC.
Clearly, I missed some posts that went away ... but while I'm not in the PML (well, I am in Spirit, naturally), I'd tend to say that a what you describe above is likely true for a vocal minority.
HINT: If they've nothing better to talk about than yours truly, then they might be part of said minority.
ANOTHER HINT: If they're worrying about my BRAND (or ways they think they can harm it), then they might be part of said minority.
But I am sure the PML is just like the broader boards and made up of all types of individuals. Oh, I see you said that right below ...
But really it's a bunch of people with varying opinions and interests who pay up to 5 WHOLE AMERICAN DOLLARS a month to support the site, get an ad free experience without short changing @wdwmagic by bypassing ads, and gossip like schoolchildren in a subsection of the forum only available to supporters. Think of it as a VIP Chit Chat area.
My only issue is a perceived superiority that some associate with that level. I do plenty for this site by driving traffic here and breaking news here. That has plenty of value, way beyond $5 a month. I support the site because I believe in it, because I like it, because I have friends here and because I believe it is one of the best places out there, if not the best, to talk Disney.
