I read with disappointment that UK tech firm Blippar has collapsed.  It is always a shame to see great talent and ideas not pulling off the potential that many people and lots of investors thought possible.

I was interested to read one of the reasons that employees saw as a reason was that there was a lack of focus. Commentators have said that Blippar never found its niche or aimed at one area to dominate.

This made me think of a question I get asked a lot by the experts I work with.  They ask 'what shall I write about online?'  

The answer is always the same - Focus on your niche expertise.  Write about the things that you want to be known for and make sure you focus, focus, focus.
