As witnessed in this brief topic,users want templates that are easy to install like the ones,I mentioned at joomlashine-simply functional and quick/easy to install should be your main focus.Creating cookie cutter templates are fine to a certian point however in todays fast changing world and with todays younger generation-with its ADD,short attention span mindsets-its very important to create a product,similiar for them.
Summary-Simple-fast/easy to autoinstall,no more cookie cutter templates-more themed based ones,especially jomsocial community builder ones,would entice me and other users to buy more templates from you-Correctly pricing your templates-lowering them,would allow for more volume based sales for your products,rather than focusing on maximizing profits,would do wonders for you.
