I don't think its a good practice to repost dynamic content here. It will be abandoned.
Hey, I'm just sharing good stuff with community. What do you mean by "dynamic content" ?
I mean that Igor is continuously working on it and accept pull requests. In 3 months that list will be outdated. If you commit to update it - that is OK. Otherwise it will impact search rankings and reduce organic growth of Steem.
