Here are the results so far:

PRLeap: %22MemeBridge+Launches+English+Language+News+Site+ for+Montenegro%22&filter=0 - 196 results

PRWeb: %22Tech-FAQ+Uses+Technology+To+Fight+Censorship%22&filter= 0 - 9,620 results

MyPRGenie(PrNewsWire): %22MemeBridge+Launches+Web+Initiatives+to+Combat+t he+Great+Recession%22&filter=0 - 8,420 results

I am not seeing significant traffic or SERP improvements from these press releases. Google may have automated mechanisms in place to discount links from press releases.
