Trawling the Net

If checking the news doesn't work for you, you can always try flicking through forums across the internet related to your chosen niche. There are a lot of places you can try, and you don't even need to become a member. If you're niche is about console gaming, just type a search into Google for 'console gaming forums' and see what pops up.

Take a glance through a few of the top results, and see if anything strikes you as an interesting topic to talk about. Are the people on the forum having a discussion about the benefits of consoles over the PC? Write a post sharing your opinion. Use the conversation and debates from forums to get your imagination rolling and start responding to the various things people on the internet are saying about your chosen topic.

This is also a great way to increase your number of backlinks. Put a link to your blog in your signature and start posting on the forum with your responses to various topics. Maybe even drop in a link to a related blog post you have made. Just be careful not to spam posts or links. If you do, you'll probably result in getting yourself banned which will negate all the hard work you already did.
