&gt; 2) Writing the answer down in a wiki takes exactly the same amount of time as writing the answer in email. It doesn&#x27;t need formalizing, just recording.<p>Not usually true in a wiki of any size (unless you mean creating a new page without reference to what&#x27;s there and shovelling the information blindly in).<p>&quot;Writing the information down in a wiki&quot; really implies doing so in a useful way. Probably:
- identifying where the information should go
- cleaning it up to remove redundancy (stuff already in the wiki)
- correcting existing wiki content which you discover was wrong&#x2F;out of date as you go to make your changes
- changing to adopt the writing&#x2F;layout style of the wiki
- etc. etc.<p>Of course its common for wikis to not be maintained like this - maybe even the norm - which is perhaps why the &quot;dump and then search later&quot; strategy of gmail, slack etc. is pretty successful.
