"Home" is the most widespread anchor choice across the web - by far - and I'm sure that this practice jumps out on any link graph that Google creates as an oddity.
Yeah, but that's only because WebmasterWorld uses it...
Take those away and it's cut in half or so... LOL.
Alright I'll answer seriously.
If it's already Home I would probably not change it, but
might.
If it's not already home I would consider a keyword or two, but personally prefer to use the domain name, so here rather than Home, I would probably opt for 'Webmaster World' being the link to the home page...
I don't use keywords too often, but do really like to use the domain name, not so much for search engines, but for the branding you can get out of the deal. Again if I was using WebmasterWorld as an example, I would prefer people not go 'Home' but rather go to 'Webmaster World'.
IMO Sometimes too much concentration on Search Engines and rankings significantly detracts from some opportunities in other areas and if one was to have the correct domain name registered IMO they could get the best of both...
Personally, I would probably not link to the home page using 'Green Widgets', but if it was my 'widget sales overview page' and starting point for my widget sales website I would seriously consider 'Widget Sales' or 'Widget World' as the link to the starting point in the widget sale process, which also happens to be the home page, so, yes I guess to a fairly good extent I agree with NOT using home as the link text to the 'root page' of a website, much as I'm sure many 'purists' who don't think about the difference in someone repeatedly reading and possibly clicking 'Webmaster World' rather than 'Home' might have on branding or brand name recognition or marketing, will disagree.
What do you do every time you click a link? You read it.
Why would you want someone to repeatedly read and click 'Home' when you could brand your website?
Think about it for a minute or three some time...
