For anyone who's interested, I've updated my draft of the letter to Mark Cuban, replacing the sentence that so offended NxtChg with:
"We believe that if you are confident in the Nxt endeavor, others will follow your lead, thus furthering our goal of widespread adoption."
Sorry, but it is still terrible

"furthering"? Is this even a word? Aren't goals "advanced"?
And "our goal" sounds like we are just trying to manipulate him (which we kinda do, but no need to draw attention to it

)
Again, this is not something we should send until we have a well-tested full-featured client.
Exactly. Let's not get ahead of ourselves. When it comes to actually sending it we will proofread it by a professional service.
