2nd RSS Survey Results



Hi all,

These are the results of my second RSS survey, conducted today. It has
more information than the previous survey and includes an analysis of
the languages specified in the RSS files. The complete element
distributions for both formats is also included. This shows evidence
of some confusion between the formats with people including <rss>
elements in their 0.90 files. Also there's evidence that some people
are including html in their item titles and descriptions. There are
also some people using <date> and <category> elements in their items.
