The posts people write in blogs can be classified in two groups: -�� those that are going to be (or should be) mainatined, expressing the real time information, -�� those that express the momentary thoughts of a writer on an event or activity.
While first ones can be managed using standart blog engines (livejournal, blogger, etc) via «Edit post» option, that’s hardly efficient. What I found to be useful is the following —�� using gist (http://gist.github.org) as a great blogging engine. Indeed, you have a handy display of Emacs Org-Mode files (the only thing I use Emacs for) and it tracks changes you do to your posts. It also has a neat timeline where all of your gists are shown in filtered by creation time. To see the activity of updating or forking gists one must refer to the main github timeline though.
