A lot of debates take place here and elsewhere but often I feel the lack of a more solid and encyclopedic goal-oriented repository. Blog posts seldom get any attention for more than a few days (and when they do there's a huge risk that they have become obsolete). So I think a more stable repository is needed.
Feel free to add to it, within the basic criteria of objectivity and neutral point of view. If you need to write subjectively (opinion article), make a subpage on the main subject and describe it as opinion article and sign it (on top).
