"...if you are hilarious about one aspect of the world and that's all you write about, people will go to that. But if it's just a grim slog everyday to read your acidic sharp little misery about something on the subway, you are going to lose them."

Yes that is one of the pitfalls of blogging, using it solely as a soapbox to put the world to rights and generally moan about stuff - therapeutic though it is, it's not always that interesting or entertaining (though I know a few blogs that make it their raison d'etre). I know I do it sometimes, but I try to lighten the mood with something frivolous too...

just a random thought
