null is not an object

I was talking to someone the other day about the observer pattern in JavaScript and I was reminded about this JavaScript method that is part of Complete UI.

nitobi.Event.prototype.subscribeOnce = function(method, context) {
  var guid = null;
  var _this = this;
  var func1 = function() {
    method.apply(context || null, arguments);
    _this.unSubscribe(guid);
  }
  guid = this.subscribe(func1);
  return guid;
}

subscribeOnce is a special sort of event subscription that rather than being being executed every time the event fires, the handler function is only executed once and then automatically unsubscribed from the event. It is obviously most useful for initialization stuff in JavaScript. There is some more info on JavaScript pub sub over on Ajaxian too.

As a way to procrastinate from more important things at the moment, I thought that I would compile my own numbers about the recently published web’s most 20 visible Vancouverites. Note that they got David Eby’s web address wrong and seem to think that Flickr is a microblogging site. I digress.

It all seems to have created a little Vancity controversy. So I figured that rather than using some secret equation as NowPublic is using I would just list some of the stats for different people from different web sites such as Google, Twitter, Flickr and so on and readers can draw their own conclusions.

Take it with as many grains of salt as you like. It is interesting that some of the people were not that easily discoverable on many of the sites that I checked yet are still considered visible… let along checking Jaiku, FriendFeed, Tumblr, Delicious, Meetup, Upcoming, Dopplr etc

I also decided to check on how Andre and myself fit into those numbers.

Clearly I am out of my league when it comes to incoming blog links but I hold my own on the Twitter front and at least have some amount of content on each of the sites listed (and more of course). On the other hand, Andre seems to be in the top 25% in each category aside from lagging in the bottom 25% for incoming links to his blog.

Anyhow, food for thought. Damn web socialites
Disclaimer: Darren does online marketing for Nitobi (so I guess it’s partly his fault we don’t have more incoming links ;)). I also couldn’t sleep last night and therefore produced this piece of garbage.
