Incorrect Article Grouping Designation
It would appears that articles are not being given the correct and relevant topic group designations, and the default being given is either 'Cloud' or 'Data Network' when clearly the article topics and content are nothing of the kind.
In short the characterisation/grouping cannot be trusted and therefore have to be ignored. The only way of telling whether an article is of interest is to read the headings.
Its all a bit of mess and extremely irritating, frustrating and above all very time consuming.
