I came across Bill's blog post on whether Twitter can serve as a personal knowledge management tool. Here's the comments about it.
I think you have raised a valid point that Twitter reminds you of de.licio.us
While Twitter is definitely good in dissemination of information, I doubt it will be useful for long term personal knowledge management.
As the amount of information increases, it will be harder to retrieve what you want. There is a limit on the amount of information that can be stored with 160 characters. There is a scientific word for this - entropy
There are a lot of meta-information that is required for a feasible large-scale knowledge base. One good way is to use emails to see what Twitter is currently lacking.
- Who - source or participants of the information
- When - When was this information created
- Context - as in previous emails discussion. Can we link up all the threads on twitter?
- organization structure - as in email folders or tags
