Recently I wrote about email overload and information removal from digital information space (for creating environment with less distractions). I came across this interesting photo of an office information overflow, which seams very real. Malone  wrote about advantages of piling or spatial management over hierarchies. The main strengths of piling are
- less cognitive effort than categorizing
- spatial awareness of information location and faster retrieval
- reminding functionality of spatially managed information
- keeping less information than with filing into hierarchies
But all these advantages disappear when there is too much information available. As in this office.
