I’m currently doing a test with Invision. 
My community is very forum oriented and I’d like to have the posibility of a forum thread being generated for blog reactions (per blog article). 
Is that a feature? If yes, how to put in the right settings for that?

There would be no way to do that. Blog replies would stay within the blog application

Thank you for your swift reply 😊

No problem at all 🙂 

I’m following up on this since this was an idea that was recently suggested within my community (and I’m disheartened to hear that it’s not possible)…

The suggestion within my community was that creating a blog entry would create an announcement topic similar to the Articles feature, allowing the blog author to choose whether or not to create such an announcement and where that announcement would appear (either a forum/sub-forum of their choice or an existing topic associated with their blog), with comment replies mirrored in both locations (Forums and Blogs). Since that’s not possible, however…

Would it be possible for the publication of a blog entry to create a locked announcement topic in the forum/sub-forum (of the author’s choice), linking to the blog entry?

The problem we have appears to be similar to that of Saskia’s community - the members are heavily focused on the [discussion] Forums and the lack of visibility of Blogs means that the Blogs, which are much more robust, are woefully underutilized. Having some way to pull members of the community into the Blogs without creating too much additional work for Blog authors would be extremely helpful.

Before you continue further, have you thought about simply adding blocks on the front end of your site? You mention trying to pull users in, and if its visibility, then this may be a way forward for you

Yes, we are considering a range of options. Having announcements was simply the most obvious solution (though perhaps not from a programming/developing perspective). We haven't ruled out any other options yet.
