It's sad that you percieve the boasting in Jehovah by zealous Kingdom Proclaimers as, bragging. Evidently you have nothing positive to boast in and so you view the happiness and spiritual pride of a True Christian with suspicion and contempt. The difference between True Christians and your ilk, is that we recognize our imperfections and sinful inclinations. Rather than throw our hands in the air and giving up our fight against selfish desires, we continue affirming our faith all the while praising God.
You see, so called Christians and that includes weaker JWs, seek to boast in selfish ways. They boast about their material posessions, their accomplishments within higher education, their prominence or social status as they want to be somebody in the world. Why boast in anything related to this system of things in consideration if it's impending collapse? Truly unreasonable! How much more sensible it is to boast in Jehovah by pioneering, or volunteering your time and skills for our projects in Warwick, NY? There's plenty of other ways to have a share in the organization. Regardless of how, when we stay busy in spiritual pursuits despite our weaknesses, we gain Jehovah's blessings and encourage one another by setting a good example. To discuss our theocratic activities and share our experiences with others is not bragging, but rather boasting in Jehovah.
