Ah, I'm past the point in my life where I care about other peoples  
impressions :)

I'd suggest reading http://macromates.com/blog/archives/2005/07/06/

As for comments, the Toggle Comment command in the Source bundle uses  
two variables (TM_COMMENT_START/END), these variables are set for  
misc. scopes (in the bundle editor), so even in an HTML file, it will  
use proper comment markers in the misc. <style>…</style>, <script>…</ 
script>, <?php … ?>, <% # ruby %> etc. blocks -- and in plain HTML,  
it'll also work.

This however require that you have the language set to HTML (and not  
PHP, which would make the scope of the entire file source.php).
