Replying a little late, but we are discussing

"technical conversations I have had with my colleagues where I can go to recover details I might not remember from a month ago. Then again email also does this just fine, and doesn't cost as much."

For static instructions like setting up a dev environment? Sure a wiki is perfect. But I don't use a wiki for technical conversations like "Hey icedchai, I'm getting an error message that the COM port is not detected and I remember you said something about solving it in yesterday's standup. Can you point me to where the fix was?"

That message is better suited for slack or email than a wiki. (Your solution might be in the wiki but I'm contacting you because it wasn't easy to find, or searching for the error message didn't turn it up).

But if I use email, then when we hire a new employee a month later who gets the same error, your answer will be in my records but not theirs.

Another poster suggested a mailing list, that is a good option that makes email viable for this.
