The problem with ads right now is that when we do attract a sidechain dev or two, the most critical component is scheduled to be totally swapped out. So, the "right time" simply isn't just yet.
Indeed, the perfect time to spend on PR will be when the new SDK is released to mainnet, which is why I've put a hold on the Lisk Awareness Campaigns... Until we have an SDK! They have begun coding it by the way... (Conceptualization phase) they are actively writing blocks of code.
I know daytraders don't like hearing that, but like our fearless wizardess Isabella says "we're here for the MARATHON, not for the sprint."

It will be something special, that much we can count on. The team is sporting some pretty hefty talent.
..looking into the crystal ball... I see Lisk making Ethereum look like the mess it really is within a year.
On 21-22 February I was at some blockchain conference in Bucharest. There were a lot of devs working on eth. Doing things for their own. There was some canadian dev that he had developed his own app on eth so he could by starbucks coffe with btc. While starbucks coffe can't be bought with btc, you can buy giftcards with btc. So he was buying giftcards and then spent them to starbucks shop for coffe. And he had an app for that. He was saying that eth was great enough for him to develop his app. So eth was good enough for him and that's great.He was not a supporter of ETH but eth was the "vehicle" he used to solve his problem.
In order to have lisk seen as an option for devs, people need to know about lisk. So, I , personally see these PR efforts ok even if it's still on its early days.
