Again: We can't update the OP as we like with only having 1 single person as a moderator. Thats why we moved the overview to the official blog. If we now add information on the OP, people will be demotivated to go to the overview blog, because they "already found information". I hope you understand this decision

I do.
But I think at least not putting this in the OP is a bad idea as people who are new will glance at the OP and assume there is nothing new about NEM.
I humbly suggest adding this to the OP: "
NEM has a 100% original codebase and over 70 team members". That way new people who are learning about NEM will think "Wow that's actually something entirely new and what a large dev team I want to check it out!", instead of now reading about NEM on the OP and thinking "hmm looks like another clone coin".
Again, I'm just a marketing professional and I know this would be the best thing to do, but I'm not angry or anything that it isn't like that right now

EDIT: Also the OP should have XEM in the title so people who are searching for XEM on bitcointalk find this thread also

Yes I totally agree with this.
Having all the info on the site so multiple people can update makes sense.
, give them a taste to want more.
Highlighting the team, # of developers, POI will give them incentive to find out more ...
