User blog comment:Cristina7/Introducing Discussions, a New Platform For Engaging Your Community/@comment-27537580-20170205013144/@comment-24258073-20170205022853

The only things about Discussions that still concern me are the discussions being so isolated from the rest of the wiki to the point where discussion posts don't count as edits, nor do they appear in Special:WikiActivity, which makes it awkward to attract users the way the new forums did.

And that only certain background colours selected in Special:ThemeDesign will show up in Discussions, otherwise the background colour will show up white. More importantly, the fact that discussions remain incompatible with CSS makes discussions look out of place on wikis that have highly customised designs.
