Most of these topics start by someone who writes one message and then never replies to the flood of posts that follow afterwards. Many of the so-called "questions" are shamless; they do not even mention the word Joomla.
Although it may be "useful" to have an area where people can discuss how Google, or Bing (or any other search engine) may index a website, if they do not in some way relate directly to Joomla it would seem inappropriate to abuse this forum category by flooding it with off-topic, irrelevant or predominantly advertorial comments about certain products that are in the public domain.
I don't want to see the forum too heavily censored but I believe that moderators should try to ensure that this category has some appearance that it was exists for discussions about Joomla, specifically, and not just webcraft in general. There is a category for general webcraft issues; it's called "The Lounge".
Examples of topics in this category that have no specific relevance to Joomla (and that would, in my opinion, benefit by being relocated to "The Lounge") are:
These topics (and others just like them) become spam-bait and no-one likes forum spam.
Of course, this is just my opinion but wouldn't it be like a breath of fresh air if these topics were killed off, closed or consigned to the great rubbish dump of history instead of lying here attracting people who have no genuine interest in Joomla like flies laying maggots on rotting flesh?
