There is a massive archive of the old-style blogs available for you to check out, which can be used for inspiration, see here: 2010, 2011, 2012, 2013, 2014, 2015. Whilst someone will have done something similar in the past, the ideas you have, and the way you present it will be entirely unique. I am really excited to see what you produce.
Note on plagiarism. By now, you know that plagiarism is not accepted at all. So simply DO NOT DO IT! The archived blogs here are all in the Turnitin database, which means that if you take text from any of these then you WILL BE CAUGHT. Plagiarism is not worth it!
