I mostly agree with a recent Big Think article [0] (HN discussion [1])
I also tell people "don't blog" [2] ...for the wrong reasons
Do blog for the right reasons [3] - if you find it too tedious to write-up your notes into a format you and others can reference later with all the "whys" and not merely the "whats", then don't do it ... but I'd wager you'd benefit from doing it :)
As I commented here [4] recently, "I presume no one reads what I write - but attempt to write as if it's being read by millions"
I can not tell you how many times I've been able to refer to something I wrote (technical or otherwise) that's helped at least myself again, if not myriad others
Also - your public-facing blog may easily be accessible even if your "notes" aren't :)
