Tragedy of the wifi commons

One of the gimmicks marketing ploys that National Express East Coast employed when they took over the East Coast rail service from GNER was to extend the onboard wifi service that GNER had introduced. Prior to the NXEC takeover, wifi onboard was free to first-class passengers, and a minimum of £4.95 an hour for those travelling in cattle standard class.

In the GNER days, the service wasn’t bad – the connection speed was generally slightly faster than you’d get using a 3G connection, and reasonably reliable. The technology behind the service was innovative, too, using a combination of GSM and 3G links to maintain a pretty robust connection in fairly hostile circumstances.

The downside if you were travelling in standard class was that you had to pay out for the service. When someone else was going to pick up the tab, I generally paid up – after all, £4.95 isn’t *that* much if you’re going to get something productive done as a result. In first class it was free, which meant that my Sunday night trips were usually productive – or at least less boring – ones.

Then along came NXEC, and threw open the service free for all. In the process, they took something which was pretty useful, and turned it into something which is actually worse than useless. Despite the increased usage, they haven’t increased either the backhaul bandwidth or the onboard infrastructure – which means that most of the time the throughput has dropped to single-figures of kbps, and ping times have increased to the point where the average is generally several seconds or more. And that’s if you can actually get onto the network in the first place – the DHCP scopes are often exhausted, and the authentication gateway regularly buckles under the strain and drops your connection, meaning you have to re-authenticate.

All of which means that travellers would actually be better off without the service at all, because of the time that gets wasted trying to get the connection working.

Porcine cosmetics, or something new?

When does “cool new features” transmute into “unwelcome feature creep”? Two of the online services that I use the most are the subject of rumours about new functionality – Flickr is apparently about to launch video support, and Skitch is to add Twitter features.

Personally, I’m pretty ambivalent about Flickr and video. I’ve never really suffered from the urge to take moving pictures, probably as a result of being subjected to too many dire and wobbly home videos of holidays over the years. And it’s not like there’s any shortage of online video sites in the first place – why build another YouTube?

But Skitch and Twitter, on the other hand, does seem to add value. I already use it at work as a quick way of sharing image edits, or annotations to a screen shot – the fact that the end results sit outside the firewall and are readily-linkable make it really flexible.

Now add Twitter to that mix, and the enhancement (I think) is actually to Twitter rather than Skitch. Twitter is beginning to take on the shape of something much more than just a cross between IM and a stream of consciousness – I can’t quite put my finger on what it is now, but it’s clear that there’s something beyond simply novelty value which has kept it popular. The subject of another post, when I get around to marshaling my thoughts.
