The plain English campaign provides a writting guide called “How to write in plain English”. I found this guide useful as it helps to write better informative text. So this might be valuable for other bloggers to. The advices provided by the guide are:

• Keep your sentences short: A clear sentence should have an average sentence length of 15 20 words
• Prefer active verbs
• Use “You” and “We”
• Don’t be afraid to give instructions: Use imperative instead of you should …
• Avoid nominalisations: Use verbs (complete for instance)  instead of their nominalisation (completion)
• Use positive language
• Use lists where appropriate

The guides provides at the end a list of words to avoid and suggests alternatives. Some words to avoid (alternatives in round brackets):

• additional (extra)
• particulars (details) 
• regarding (about)
• terminate (end)
