This is my opinion so please take it as such.
As a MSP who utilizes several servers for different clients I hate that Thwack is a default addition to the summary page and the menu bar. Every server I setup I remove it. My Orion servers are to monitor client networks only. Myself and the members of my team can go to the Thwack site on our own without it added into the Orion server. While I truly value the Thwack forums and think they are a great tool I don't need them on 9 different Solarwinds installations.
