There are some projects which already have fast TPS but are not blockchain ledger or had to compromise security to make it happen.  It might be notable among some nerds if NEM can attain 1300 TPS on the public chain and it'ld be the fastest secure blockchain.  Still the 'investors' probably not notice.  Investors are irrational and most are following FOMO trends. 

Vitalik Buterin could pour organge juice into small plastic rings and put it into the freezer, claim invention of Ethereum-Popsicle, and investors would buy Ethereum mad. 

Still I don't see fast TPS bringing in new users.

For adoption to be on the up, I think NEM needs the following.

Public developers - I'm talking about Jaguar0625, Gimre, Bloodyrookiee and Thies, if Thies is still around or not.
Foundation is formed.
Trollbox post campaigns - like forum signature campaigns where you get paid to post.
More community organization out of Japan / Malaysia.
ICOs, based out of the NEM developer funds, could create some publicity too.

And im sure we will see this happen with the new foundation formed.
They have been requesting everyones skill and expertise, and i encourage everyone to submit their skills.

Im hoping I may be able to speak at any future events held here in New Zealand

And yes, a poloniex trollbox campaign would be excellent, we have to be careful not so spam heaps, but if we can arrange a set time to all mention NEM there, it would do wonders, I myself have already got people to take a serious look at NEM on the trollbox, so its a good idea for sure.
