The sharing economy

Is the sharing economy at risk of becoming derailed by a few large Silicon Valley corporations? Chris Martin fears so, but his research suggests alternatives might be difficult to get going:

There are some downsides to running a democratic platform, however. The most prominent being that Freegle’s democratic model has made growing the network even more challenging than it might otherwise have been. Lengthy decision-making processes, based on discussion and voting, have meant that opportunities to expand have been missed.

It also means that financial backers geared toward supporting more streamlined for-profit companies have been deterred from investing by the complexity of Freegle’s structure. These issues suggest that efforts to create a more democratic sharing economy may face considerable resistance; in particular from actors with a more commercial focus.

Four Things: The Augmented Fourth

Because (except in Scotland) this is a four-day week, we're marking the week with a collection of four things related to the number four. It's the sort of idea you come up with the morning after a bank holiday. Yesterday, we focused on the Four Freedoms.

Today, we're looking at the Augmented Fourth. This is the musical interval f-g-a-b. It's different from a diminished fifth, which is b-c-d-e-f. And obviously it's not a perfect fourth... You know what? It's probably easier to show you:

The discordant sound of the augmented fourth led to it being dubbed "diabolus in musica" and was banned during the Renaissance from being used in church music. But it doesn't have to be painful - it's used, for example, in Maria, from West Side Story:

Not so devilish in the right hands - although not easy to sing.
