Don't just type, talk to your audience. Blogging is way big a market on internet and people will like you if you do more than just providing information. Suggest, express, appreciate, criticize and have an opinion to build a relativity to a like minded audience. Make them feel that their visit to your blog matters to you.
Audio Copy - Making an audio copy of a blog post is a great way to market your content. You can use it to share on a podcast feed. It is easy, fun and mobile.
Presentation is as important as good content. Have attractive pictures, fonts, etc. on your blog to hook the reader.
