Since this post was made, the pound has slipped about 10 cents against the dollar. Perhaps that's a bad month, perhaps a sign of a longer trend as Brexit worries start to bite yet again. Who knows? Forex markets are weird and I still don't get them.
Still, it was interesting to see this post -- I thought around the time that the pound crashed following the vote you were one of several explaining how a low pound was wonderful because it was good for exports. If so, isn't the recent increase in the pound a bad thing to see? Or is this one of those times were every move can be explained as good news, depending on what cherry-picked benefit suits you the most at the time?
Really, the story of the pound's rise against the dollar is about the weakness of the American currency, rather than the strength of Sterling. As ZM pointed out, the pound has been largely flat against most other currencies, particularly the Euro, since 2016.
All of this is complicated and is essentially the market responding to uncertainty, and that still is going to be the case up until Brexit, and what that actually means financially, is understood. There are plenty of other effects, and twists and turns to come, before then.
