Thanks for installing it :)
The HackerMed theme is specific to the HM site, so it won't be included with Noostr. However, when 0.7 is released (supporting categories), there will be a theme section here so you can find a theme you like and use it. Noostr is written to be as easily themeable as WordPress is.
The default theme will also be updated for 0.6 and 0.7 to show off most common features, and when this site is updated to use 0.6, there will be a page specifically to help people theme Noostr.
In the meantime, if you do a "print_r($ns)" in your theme somewhere, you'll see all the variables currently available to the theme ;)


A timestamp-to-words function has been added to the default theme now. It seems to have a small problem (displays "an 1 hour ago", for example), but works and will be updated in 0.7 again.
The "$ns" object has been extended as well with some new variables for themeing.
