While there's lots of good stuff on technology-based lifehacking, what
about low-tech stuff? I think back to articles on things like the
hipster PDA and wonder how many other people found the concept of low
tech productivity tools interesting and/or useful.
For myself, there are a number of low-tech options that I've seen or
been working with that have made life a lot easier... everything from
a little leather notecard pad with an accompanying desk notecard
display case to business cards used as note paper to little postcards
that I discovered I can send myself as reminders when I'm away on
vacation and have an idea I don't want to lose.
I'm guessing there are lots of these that are used regularly by people
which would make for interesting additions.
