I wrote the below post a few months ago and think it’s important to keep the message out there. Steemit is still in Beta and obviously very far from perfect. I do think there is a fundamental flaw in the expiration timeline and the search functionality that makes good posts undervalued. Until something better comes along authors should not be afraid to update and repost their work.
Now that I've been on Steemit for a few months one of the obvious flaws of the platform is retrieving quality information from previous posts. The Google powered search engine tends to pull up the oldest posts that are not necessarily the most relevant and/or is dated information. Many of us resteem certain posts simply to be able to find it again for reading. The nature of the payment system is a double edged sword. It encourages people to keep creating but this has a tendency to burry quality posts fairly rapidly. Another issue is that new members of the community may produce excellent material that is never seen and conversely they may never see other's useful insights that are now hidden in the archives.
Humans tend to have biases that would make us feel as though reposting old material is a bit like double dipping. Would an AI be biased in this way? NO! Would you prefer radio to never replay a classic tune? Wouldn't it be silly for a school teacher to refuse teaching a subject because they taught it the year before. If it is good info and it benefits the community then repost it rather than letting it die! Much of the info related to crypto might seem like old news not worth reposting to a person who is constantly following the space but IMO the good posts deserve several lives over the course of a year. If you get to make some Steem twice be proud that you've produced something that people still want to read! You are doing the platform a favor! So go through your old stuff, update where necessary and put it back out there. Steem is growing with new readers everyday! Better to have quality than quantity.
