I would much rather see a more mnemonic approach for links, where you would write either _click here_ [http://wherever.com http://wherever.com] or _click here_

I would much rather see a more mnemonic approach for links, where you would write either _click here_ [http://wherever.com http://wherever.com] or _click here_ (http://wherever.com http://wherever.com). The underscores look like an underline, which is the traditional appearance of link text in HTML. It's easy to remember. Whether the URL is in square brackets or parentheses (maybe either one would be acceptable as long as they are a matched pair) doesn't matter, but underlining the anchor text is the way to go, IMO.
