When I first jumped into the exploration of ping.fm I thought that it had one application for me. I had just figured out how to use twitter as a hub, and now ping was trying to throw off my groove. I quickly concluded in a previous review, that the only reason I might use ping is if I wanted to get a quick webcam video out to my networks. Seesmic works with ping in that way in a very easy flow.
Then I added the synergy of twitter feed and my opinion has drastically changed. With these two tools working together, Ping works as a hub that I don't have to visit. It works as a background resyndicator of my content. Here's how I use the tools to sync together...
If you are going to try this out, and you don't already have profiles on some of these services, I would recommend starting with getting yourself an openID. An openID will be something that twitterfeed asks and directs you to early on in the sign up process. So, while you are at twitterfeed, you will choose to pull/push your twitter and your blog feeds. The rest of your profiles will be tied in when you open up your ping.fm account.
If you are just going to simply test this work flow, and you don't have any existing accounts, start by opening a quick email account with gmail. Don't use your productivity email account to simply test these services out. You don't want to accidentally take a potentially usable user name off the table just because you are playing around with the technology.
ALSO - THIS IS NOT A STRATEGIC RECOMMENDATION!
There can be all kinds of reasons not to follow this schematic. Most of those reasons have to do with a series of strategic questions you should ask yourself about why you are participating in these spaces to begin with. Your strategy should inform your schematic.
And, by the way, feel free to use the image however you want. I haven't dug deep into Beth Kanter's advice about the Creative Commons License yet, so the image isn't labeled properly, but feel free to take and use. I hope you can show me your own schematic work flow.
