Doing posts about the same subjects is inevitable, there are notminfinity subjects, but there are almost infinite ways of expressing opinions and thoughts.
Anyone can add value to this blockchain by sharing their ideas with the community, or in the case of developers, by sharing their code and tools created.
Every person has their own unique way of thinking, by sharing it, your are contributing value to the community, even if the subject was already discussed by another user.
That’s my opinion! Cheers!
