Follow up on comments you wrote on posts. Continue the conversation. Bloggers enjoy engaging with their readers.
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.
Be awesome. There's enough mediocrity out there. Stop adding to the noise and do something outstanding.
