@Mary996 many new people come and participate here all the time. There are lots of newer posters who give really good advice. People come and go. If you feel people's responses are of no value to you because the responder has been here too long, don't take their advice, I guess. I'd rather take my advice from seasoned hosts whose responses are relevant and well thought out, and who are operating in good faith, regardless of how long they have been here. It's a community made up of individuals who want to contribute, not a board where someone gets to tell us we've outlived our usefulness.
There can be damage done when people get the wrong information or bad advice. It's not a game or a popularity contest: real people come here for help, often when they find themselves in difficult or distressing situations. Stuffing the ballot box or compulsively liking someone's posts regardless of whether they are correct or relevant because you like them as people doesn't help.
