Sorry for the late reply @veleje, I totally missed out your comment, since I was a bit busy. I hope you see this.
If you want to get the new posts a simple modification of the code will do it, just change the URL in the code like this:
browser.open('https://steemit.com/created')
Since all the new posts are listed in the URL : https://steemit.com/created
Hope that helps.
I am currently in the work of Part 2.
Once again sorry for the late reply.
