As i get older, i learn to despise all forms of mediated communication. The problem is that context is lost. When i look focused, my roommates know not to interrupt. With mediation, i can usually cue people that i can't IM. But then there are the spammers. They've invaded. Every. Aspect. Of. Mediated. Communication. We've got the telemarketers and the junk mail. Email is crawling with them. I turned off SMS because of them. Hell, i have to do blog cleansing more often than car flyer cleansing these days.
A key problem for our knowledge society. Indeed, when I use personal communication tools like e-mail or weblogs, my fundamental liberty is too be able to choose the community I am communicating with. Every identity I have (as a citizen, father, employee, friend, painter etc.) is within a community. This identity is reflected for example by the e-mail address I use and the website behind the address. This web site is associated with my identity as a corporate knowledge manager. Is is a public site, which means that anybody in the world can quote me on what I write here. On the other hand, I don't welcome any comment which is not relevant to the topic (and I do have a lot of those). In the future, I may have a semantic filter that will eliminate as spam any comment made on my weblog that is irrelevant to my identity here, even if it comes from my wife. Same for e-mail.
