a good friend of mine drew my attention to the WhoopCast Network.
according to its mission statement, it's a site which aims to develop the "biggest and best directory of Asian podcasts".
i especially like the fact that they've got a dedicated section at their site dubbed the 'School Zone'. no doubt it's not very well populated just now, but i'm sure numbers can only go up from here.
(and if you're wondering, ventriloquy is listed under the 'Singapore Channel' :-) )
