yeah, but what do you do if, despite cajoling and management emphasis, none of the damn programmers want to use the damn things? they seem to feel the code is self-sufficient.
there's learning on an academic track timeframe, and there's learning. there are lots of courses i took which i did not do well gradewise, but i learned a lot, enough to go back and re-learn the material at my own pace and better.
yeah, like while i admit it's possible, why would businesses necessarily gravitate to a platform which has the image of being for teen and young adolescent dating?
i know they're not free (as in beer), but there have been networks like this around for a while, and they have not become business platforms, even if they are "more serious". i'm thinking of linkedin.com.
i'm not trying to scrap, merely to understand why people think this, rather than believe such notions are matters of early -- and justified -- enthusiasm.
