Unlike a traditional blog, a lifestream incorporates and archives realtime interaction with information streams from disparate sites and web services. As you scroll through the contents here, you will notice that items from approximately 20 different sources appear in different color themes, along with their respective favicons in the top left corner of each posts. Direct entries like this one, of course, display the favicon of my site. You'll also notice some issues with CSS not quite displaying imported white space correctly in every case; hence, it's a work in progress.
Of course, lifestreaming and lifecasting are nothing new; however, like most new technologies, it can take years -- even decades -- for technological capabilities to become quotidian actualities. In terms of Augmented, Extended Cognition and Attention Management, we've made good progress on many fronts, yet pathetically lag on others. I suspect that the rise (and fall) of the various walled-garden and proprietary micro-blogging sites, the momentary loss of tr.im URL shortening, etc., may finally provide the next impetus for more people to take individual lifestream and link management more seriously; e.g., roll your own, and similar tools that enable non-programmers to do the same. I've presented some of these thoughts in more detail in conversations on various forums and in earlier posts; which serves to point toward one key opportunity for improvement of platforms like Sweetcron or the lifestream Wordpress plugin: the ability to easily find and reference those posts by some kind of Ubiquity-like overlay WHILE I'M TYPING this entry, rather than manually searching through bookmarks, sifting through tag clouds, or navigating other archival hard links to said items.
