Sometimes I can be on writers block, which makes it particularly hard for me to continue with my blog. I visit YouTube and type in some of my key words. Most of the results will be reviews and tutorials. I watch the most interesting videos and decide if I'll write an article about it. Watch the video from the start and copy the content into Word or a notepad if that helps you. I know that I'm a particularly slow writer so I have to pause it every now and then. The content you write down probably isn't yet recognised by search engines. Do some tweaking so that it is interesting to read and BAM. Post it on your blog.
