Both asterisks and underscores achieve the same goal, but the author prefers
the asterisks. So too, apparently, the creator of Markdown, John Gruber. He
was reported to have said:

    "Asterisks were never in doubt. Underscores were added as a secondary
     syntax because enough people seemed to use them in email."

This may conclude the automated conversion of tag descriptions. Additional
improvements will probably require manual edits that take full advantage of
the Markdown feature set.
