del.icio.us has been heralded as a classic example of the sort of application that is “Web 2.0” but until recently I could not really see the point of it—web-based bookmarks? However, having been something of a computing nomad these last few months, without permanent access to an always-on, always-connected server of my own, del.icio.us has proved a useful way of storing random bit of information that I have needed to be able to access in a variety of places; e.g. links to products I have been recommended, technical information I may want to retrieve in a different location in the future, etc. As with any storage system, the make-or-break feature is retrieval, and Gmail-style multiple keyword-tags and a search facility look sensible and useful.
