Chris! Wake up! This is a forum on the World Wide Web. Those tips go for *all* published material using links - from HTML to RDF.
Its not subjective - if you put your eyes out in a freak fork accident, you'll thank me from your screenreader!
If you use a decent browser, like Opera, you will have access to a links tab: That information is basically all that a blind user/search engine can see - if its "here", "here", "click here" then it makes no sense out of context.
Search engines pay more attention to links - link titles give clues about what a document is. By doing this you are helping index relevant topics for robots, spiders, and other programs which read these pages - and providing pointers for keywords.
I hate using the search feature on these forms because, try as it might, its no google. Its fairly straightforward and works off of a simple query - google is far faster for searching these forums for relevant topics. If you optimise for google/search engines, you are benefitting the WorldWideWeb as a whole. Google results for "here" on mIRC Forums Google results for "COM Object" on mIRC Forums
Imagine if all of the "here" links were labelled better with a title - you'd jump to definitive posts after following only two links - or less. Instead, we have a bunch of plain text results for "Com Object" - so "Tutorial on working with Com objects" is listed with "I was haxxored by com objects plz help what do I do warez pron moviez" - the first result is going to be far more likely the 'more relevant' link; but gets the plain old billing with the warez/porn/hacked by link.
