People in-the-know know what company and people are being discussed in these posts. Accordingly, "I know privileged information." banter is thrown around.
I wish that, for the sake of those outside the loop (me at least), people either name-names or take the wink-nods to a private message.
This is probably going to be a very unpopular (ie: negative karma) rant, but those of us outside the SV echo-chamber get hit by this all the time.
