If it wasn't for family related things I would have closed my Facebook account years ago. But, as it stands, there are sometimes posts I need to see and react to.

That is the only use Facebook ever gets from me so they really have no data to present me with a meaningfully personalised service.

It can be quite amusing seeing the suggestions offered up as people I might know. If I accepted even half I think I'd be connected to almost the entire population of the Philippines by now.

Twitter, however, is different and I'm not entirely sure why. Although I've not actively tweeted in over 6 months, and am undecided if I ever will again, I'm strangely attached to my Twitter account.

Maybe it's because I joined back in 2006, the year it was launched, and am proud to have an account that old. Maybe it's because I know what Twitter could be and I'm just holding back until something changes.

Or maybe it's because there's a fundamental difference in the way I see and personally connect with the two services.

Many complain that Twitter doesn't know them, even after years of posting thousands of tweets. However, compared to the mountains of information held about us by Facebook I think this is quite refreshing.

It also illustrates the different purposes of the networks.

Although we can tailor our Twitter feed by following/unfollowing people its purpose is, ultimately, to show us "what's happening." This may occur partly in line with the parameters we set but it is a more specific goal within a much wider context.

And, to me at least, that is a far more attractive proposition than the blatant 'entrapment' within the network employed by Facebook.
