Just drop it
What connotations does “drop” have for you? As far as I’m concerned, they are negative – you drop a bad idea, for example. Or you might drop your drawers if you have to reveal that you have been caught out. Sales drop off, if a product isn’t successful. If you drop a glass, it usually breaks.
So why on earth would anyone want to call a platform to spread know-how Dropping Knowledge? My guess is, it was invented by non-native speaker of English. It sounds slightly more more positive that “Dumping Knowledge” I suppose…
