I agree 100%, I'm a 'Newb' to Steemit and am actually SHOCKED to find out that I cannot edit posts after 7 days. I'm an experienced and successful internet content creator, and one way to get your content READ is to create posts that are 'placeholders' for all of your other content, sort of like an 'outline' or 'introduction' to all the topics on a particular subject that you will be expounding on, then as you add articles on that topic, you 'interlink' all of the content together.
Not only would this benefit content creators, but benefit Steemit because people would stay longer on Steemit, which is part of Google's algorithm.
It's silly for Steemit not to allow this feature that would not only benefit content creators, but benefit readers, and also be more beneficial for Steemit in the search engine algorithms.
With this method of interlinking my related articles, my visitors read, on average, 3 pages each time they visit, as opposed to one and, at most 2, for most sites.
Also, as mentioned in the OP, Steemit will become a site with HUGE amounts of dead links, which Google also dislikes. MANY people tend to make articles that point to authority sites, such as research studies. These sites change their site structure over time, making dead links a problem. The ability to change dead links is imperative to the making of a good website, and, again, Steemit is 'shooting themselves in the foot' by not allowing the updating of dead links, since Google frowns on such things.
Steemit is hurting themselves as well as us, by not allowing this feature. Who wants to read old, outdated information with dead links. By updating my site constantly to keep the content fresh and links updated, I have been able to keep pages #1 on google for years at a time. But if I allow my content to become outdated and allow links to become dead, I quickly lose my favored google position.
Steemit is INTENTIONALLY allowing this to happen? Seems dumb on their part.
GREETINGS, my new friend @kerriknox,
Thank you so much for your very comprehensive and supportive comment.
I really appreciate your added support, and hope that you will join in raising awareness of this issue.
