How much noise must you tolerate in a social network to attain a reliable set of responses to your posts? Would the content and value of those responses be sufficient to balance the “wheat vs. chaff” formula in your network? What’s that magic number or ratio that marks the “critical mass” of your network to essentially guarantee feedback? Should such an objective even matter to you? What about privacy concerns?

This is a philosophical thought exercise I’ve been bouncing back and forth in my head for a while now. I call it the conundrum of critical mass.

You can keep a smaller, more meticulously pruned network to have stronger control over whom can view and comment on your content, but you suffer a larger chance of being lost in the crowd. Or, you can expand the network to whoever’s willing to join, but risk having to wade through the waterfall of content coming your way and deal with folks commenting randomly on any piece of content you post. Sure, you can tweak your settings to view only the specific folks whose content you’d like to read and interact with (which helps with the input on your end), but it can be more labor-intensive to adjust which members of your network can read and interact with your content.

The risk of the tighter network model is that any of your given posts have a higher risk of missing the mark. You have a smaller audience, which could result in either 1) the post wasn’t interesting or relevant to them, or 2) they weren’t online when it was posted and it’s lost in the stream of posts from their other friends.

Or, you can play the indifferent or uninhibited cards and simply not bother to care. There are plenty of folks on Twitter, for example, that will just ignore the vast majority of mentions and direct messages from their followers, even if they’ve made the effort to follow them back.

Yep, I realize this post is self-examination. I don’t claim to be a brilliant, witty, or inspirational person (despite what you may have been told), but it’s the interactions between individuals in social networks that really interest me. I’m always curious to know what content gets people interested and engaged without coming across as chatty or self-serving. At the same time, I’m constantly conscious of the privacy implications in social networks: basically, avoiding whatever content would be sharing too much.
