Value your content
The first thing you should do today is backup your content - wherever you posted it, if you care about what you wrote, go ahead and back it up. I'll be waiting here.
While you're at it, go buy an external drive to backup your own hard drive. I lost two in crashes, so I know what I'm talking about. External drives are relatively cheap compared to the value of your work.
That's how valuable I think your content is. And if you take the time to cull information, research topics, and share what you know that content is even more valuable. Value it yourself. Content is the currency of the Web and the gateway to social capital.
Build outposts
There is a balance you can strike between curating your site and participating in social networks. Building outposts in sites like SlideShare, Facebook, FriendFeed, Twitter, LinkedIn, you get the idea. There are other kinds of outposts that are not online, but do make their way there.
For example, are you attending a PodCamp or a BarCamp? Those events are highly documented online, and you get the advantage of live conversations with people you might have met online. Communities are another kind of outpost. For example Marketing 2.0 built with Ning, and many others.
With outposts, the content you create helps the community and it helps those sites grow as well. So remember to farm your own field first.
Subscriptions
Many have written recently about the demise of RSS. With sharing on sites like Twitter and FriendFeed, we are relying more on human filters. We pay more attention to what our network reads than we ever had before. We did the same with television, didn't we? It's part of what makes us social to have the same reference points.
Subscriptions are not going away. I'm in favor of RSS and a big user. With services like Feedly and (now defunct) Google Reader, they are becoming an integral part of the conversation. I've been using Google Reader for a couple of months now. It's much easier to track what people are posting about and the community reactions with it.
If you want to keep up with what I'm doing, subscribe to Conversation Agent. This is where you'll find out about new eBook projects, community initiatives, what I'm working on, and the people who are doing great work in my network. It takes more than 140 characters to express something that could benefit you.
Staying in touch happens also by email. What I like: short, to the point messages that clearly state up front what you're looking for. Be honest. Please don't beat around the bush. That's a surefire delete. What I don't like: press releases, attachments, vagueness, and bait and switch tactics.
What about you? What gets and has your attention? What do you need to work on?
UPDATE: when a site has RSS, it's making it easier for you to syndicate the content to a reader, not another site. It means real simple syndication, not "real simple stealing" (got that from somewhere).
