Longyearbyen (Largest settlement) has got on the order of 2,000 inhabitants which basically means that in a few weeks, all the faces are familiar and the ones which aren't are tourists.

Now, this obviously leads to a close-knit community and isn't inherently a bad thing - but I'd find it a bit claustrophobic in a while. (Doubly so if I was single, as the dating pool is very, very limited.)

The scenery is hard to beat, though.

Fun fact: Part of the deal when Norway gained sovereignty over Svalbard was that anyone from anywhere could settle there without bothering with visas and the like - as long as you can provide for yourself. (This, admittedly, is somewhat more difficult than it sounds, as just about all housing there is is owned by the Store Norske Spitsbergen Kullkompani, the coal mine which until satellite communications became a thing was Longyearbyen's raison d'etre - so finding shelter can be a challenge if you decide to give Spitsbergen a try)
