The flavour of the font is rather mixed. Its monolinearish, but has tiny bit of contrast (which increases the legibility a little in Mac OS X) In order to support windows users, smaller sizes 9,12,14,16 pt are painstakingly hinted in Truetype format.
The name Arvo is a typical Estonian man's name, but is not used widely any more.
In the Finnish language, Arvo means "number, value, worth." Considering how much programming is behind hinting, 'number' is also true.
