Writing on a pre-defined theme has never been my cup of tea. Even at school, writing an essay meant facing an hour of total lack of inspiration, and coming up with something - in readable handwriting - in the half hour or so left.
This is what the IndieWeb Carnival reminds me of. I have waited for the good part of June to even begin to write, and I have five days left before the deadline (though Andrei - the host for this month - has kindly extended the deadline by a couple of days).
