The last article took me 4 hours to write. I have expertise in the subject matter, which makes it easier and quicker, but had to do the research to find the quotes and cross references and read the supporting links to ensure relevance. The population data came from google sources and wikipedia. There are nearly 1400 words.
Is this slow or fast? Not sure, but it was more than the ½ hour that Boris Johnson claims his chickenfeed column in the Telegraph takes him to write each week and I get £250,000 less than he does for it.
