I received a request from a reader today to put out the call to people who use an index card system (aka "Hipster PDA), especially anyone who has used this method for a long time. She would like info and advice.
Personally I've never used an index card system, but I've seen them around online and some people have a lot of success using them.
Do you have any advice on using an index card system? Please post a comment, and thanks in advance!
