A Friday Question: Do We Need Platformism?

This idea is sure to rile some people up.  We are all familiar with the concepts of other "isms" where we are judged based solely on looks, race, physical appearance or some other subjective measure.  Sexism, Racism, Elitism ... these are things no one likes, and most educated people know these are wrong.  The issue many people have with blog measurement tools at the moment is that they apply the same unilateral notion of equality to all blogs and URLs.  Blogs done on Typepad are searched the same as those done on LiveJournal.  Dotcom URLs are weighted the same as DotInfo URLs.  what if this weren't so equal?  What if having a dotcom URL actually meant your site would be taken more seriously?  What if standard searches for corporate brand mentions excluded sites on more personal platforms such as Livejournal, Vox or Blogger?  Judging blogs without understanding their content is what algorithms are made to do - yet the problem with most is that they simply take terms that are mentioned and offer back jumbled results.  Just go to Blogpulse and type in any brand name you can think of, look at the search results and you will see what I mean.  In a world where URLs and platforms mattered more, a choice of platform to use would be based on reputation more than price or any other factor.  Would it be good or bad to live in a world like that?  What do you think?
