by the way i hope u gonna find your link exchange partners ..and i guess your site getting much more hits since u have opened this topic
but why didnt u use tags ? or just i didnt see them in the topics ..it's really necessary for your seo and search engine hits.i guess u use your categories like tags but they are different missions .if u have used 5-6 tags u may just pick 1-2 categories for your posts..this gonna change many things like your hit, seo , pagerank..etc
