massively obvious online denial

It's interesting to see a common category emerging: slacktivists and
slackademics alike finding it easy to say "yes" to things online, and
then not having the wherewithal (or the motivation) to follow through
in any way.

Of course, this happens offline, too: February is the season of failed
New Year's resolutions. The question or issue is not just "why", but
what if anything can we do about it!
