Promoting Macintosh specific Web Sites is a fairly easy task. Even programmers who have their programs developed for the Macintosh too can take advantage of some of these resources.
Post consists of a lot of links to Macintosh media and news sources. Sending a little note, a little press release or dropping a link to them can do wonders for your site. This concept can be done for any site, couz this is Mac specific topic here are a few good resources.
Instead of dropping each individual link to the site I will refer upon DMOZ structures which contain a lot of sites, feel free to add any to this list if they're not in dmoz already.
