True. And if it was a "Phone" forum MR would soon be overtaken by Android fans.
This is it. As a moderator in another place (
http://www.clubdelphi.com) I understand the issue. Is summarized like this:
Build a place for alligators and they will come.
A subforum is like open a new bar in the town, that say "All people interested to find people to think this way, here".
I bet that build a android-focused sub forum will increase dramatically the # of android-only users that will come here. So, will increase the undesired effect that the OP express.
And a VERY good example is the political/social sub forum. MC is the
only tech forum I know that political/social (or how I summarized: Atheist VS Theist, Dems VS Rep + Gay related stuff) dominated so furiously the attention grab. Because I live in Latin-America, I find entertainment and sometimes informative the sub forum (when talk about news non-related to the battles I outline before) but still.
So, I visit this daily and ALWAYS a social/political stuff is in "Todays post". I can't remember a day where this not happened (probably exist, I'm talking about impressions, not facts). How interested I'm about such thing? Zero.
Because EXIST a place for it, the people/talks find a place to call it home, and make it big.
Especially if is a topic where a significative number of people want to discuss & trolling.
