I've decided that the hassle of checking in at various places just isn't worth it. Sure it was fun for a while to collect points, badges and mayorships, but in the end there's just nothing in it for me.
If I lived in the USA or in a big city where there were loads of special offers it might be worth the effort. Even the joy of being mayor of my local pub has worn off now, so that's it.
I welcome the relief of not trying to outscore friends and being able to appreciate a venue for it's own merits rather than how many points it's worth.
