@silverpill @icedquinn @p @frogzone @nimda It would've been easy if the URLs in the tags array also contained the remote URLs, then it'd be just a simple string replacements. What's confusing is that that's how it is for mentions, both the links inside the post HTML and the mentions object array contain the remote link.
So far I've avoided using and HTML parser and I don't think the hashtags are important enough to worth the extra bloat.
