Map Selection: I never get certain maps

[[PETA] Cor13:4]

I know random does not mean equally distributed, but looking at the OSN records, I rarely get certain maps, while others I get a whole lot.

For instance, of my 61 or so games, only 1! has been Long Nine, while War Garden, which is newer, I have played 9 times.

Map distribution:

Long Nine: 1
Foundry: 9
Glitch: 5
Peekaboo: 5
Reaper: 4
SkullDuggery: 1
Sharkfood Island: 11
Sweet Tooth: 3
Sweetie Plains: 8
Thorn Gulley: 5
War Garden: 9

It's likely just the randomness, but are there certain maps people like to play that get selected to be played more often (1st player can map select), or is the randomess broken? I'm rarely 1st player, so I didn't map select this distribution. (I've map selected as 1st player to prevent a SvS gruel match on Peekaboo, so that statistic might be slightly skewed).

I guess I should check OSN and all maps played if I really wanted to figure it out, but I wouldn't want to do that manually =P
