One problem that I see a lot of bloggers falling into the trap of doing is simply writing what everyone else is writing about on their blog – and doing it in the same way everyone else is. The term ‘echo chamber’ comes to mind.
I think we’ve all done it (or have been tempted to) – a news story breaks, we report the news, perhaps with a quote and link from another source and we’re tempted to leave it at just that.
