You're on Facebook. And maybe you're on LinkedIn too. I tell you something: it's not enough.
Hundreds of people won't find you on their favorite social network. Some other people cannot spell your name correctly and don't know what to search on Google. A few know your name, are connected to you but don't know you're blogging somewhere on the web.
Even your closest friends are missing something about your online persona. And it's not good for you, because maybe the will find something interesting and can tell you something you don't know about your niche. Don't you believe me?
An old friend connected to me on Facebook, and asked me something about what I've written on a blog. It was an interesting conversation and I had a great time talking again with him. I put all my blogs on my Facebook URLs so everyone can easily check all my online spaces. And I put them on FriendFeed too!
I've been using FriendFeed for a few weeks by now, and I think it's very useful because it can do a very simple thing for me: track all my contents published on the web (serveral blogs, delicious, youtube, twitter). Although it can be a conversational social network I use it in a very basic way: I just put my RSS feeds in it and it does all the rest!
I post on twitter, save bookmarks on delicious, publish video on youtube and write on several blogs. My friends probably visit two or more of my blogs, but still not all of them. My random readers will probably visit just one of my spaces. So, both to the first and to the latter, I can suggest something I've written that might be worth to read.
Here's my advice for you: try to inter-connect all your social spaces between each other (via a simple link) and use some aggregator - like FriendFeed - to give a unique stream of all your social media. You will get more readers, and you could offer a good service to your loyal followers.
Feel free to add me as a friend on Facebook, btw.
