Sharing is caring (to a certain degree), if your sharing is not just pure bragging, the I can see only positives on it. E.g. somebody sharing on how good the food is in a new restaurant is genuinely happy about the experience and wants his friends to check out this restaurant too, as they might like it as well. This is good motivation and basic human nature . Vs somebody that goes in a very expensive restaurant (that everybody knows about) and shares just to brag about it/ show their social status (this might just elicit envy from their friends, another basic human emotion). Delivery style and context are very important in this case. On the other hand I have friends/ acquaintences that don't share at all and just keep it to themselves. To me this is selfish and just as bad as over sharing. A good friend will share both good and bad news. People that share over selectively, or dont share at all are on the selfish side.
