'Daily' is just a place to add a few snippets of information about your day to day life. What you have carried out during the day - or what you intend to carry out during the day - will no-doubt be of interest to others.
NO PERSONAL INFORMATION!
Don't divulge anything that could compromise your lifestyle in any way. Don't go mentioning you are off on holiday for a while for instance as this could inform 'nasties' your house is likely to be empty.
Always post with caution in mind. The world is far from safe these days.
