Lately, I have been talking to quite a few folks about how to setup your own personal publishing system. There is no shortage of platforms for an individual to publish content on the web. There is also no shortage of tools which can distribute your posts to other sites. Without planning, the whole system becomes and echo chamber and your message gets bounced from one service to another. Some services will get the same post multiple times, which leaves the message that you either don't know how to manage you publishing or don't care about wasting each constituent's time.
The answer is to do an assessment of your publishing and distribution strategy.
Publish
Make sure you map out how you create original content. For example, here is a generic process for publishing.
Participate
Identify the properties that you want to participate in. Each property has it's own audience and characteristics to consider.
Facebook - Primary for personal interaction, I try to only use Facebook for connecting with people that I know. I keep the flow of business/technical items to a minimum. Links in Facebook feed to Friendfeed.
Twitter - Quick thoughts and links to interesting sites, feeds to Facebook and FriendFeed.
Delicious , Digg, StumbleUpon - Quick bookmarks feeds to friendfeed
Posterous - Main blogging platform, where I post more in depth content feeds friendfeed.
Distribution
