I'm getting a little tired of the way the welcome beam and the welcome speech are being abused. They used to be a friendly way to welcome newbies; now they're just a moronic way for immature forumites to inflate their post count. I get the distinct impression that most of the serial welcomers care too little about the person being welcomed and too much about the complexity of their welcome speech and the number of times they've posted a welcome first.
It's also undoubtedly annoying for the first-time posters. When I see a thread consisting of a question, five welcomes, and no answers, I can't help but think the newbie will get the impression that we're all show and no substance. Welcome speeches may make us appear friendly, but it's content and answers that will convince people to stay.
So I'm going to start cracking down on abuses of the welcome beam. If your welcome speech is too long, your post may get deleted. If you commit a serious infraction -- like if your post consists of four welcome beams and three paragraphs of text -- you may get temporarily banned.
As a rule of thumb, your welcome speech should not be longer than your substantive reply to whatever the thread is about. It certainly shouldn't be the only thing in your post, especially if the newbie's question hasn't been answered yet. The only exception is when a newbie posts a pure "hi, I'm new here" thread, with no problems or questions. If he has problems or questions, he deserves an answer.
Many of the moderators, such as karajorma and Taristin, share a similar opinion, so I imagine they'll start doing the same. Consider this newspost a statement of intent -- more than a regular post, but less than a change in policy.
