There are a couple of ways that files can be offered for download from a web site. The simplest way is to offer the download using a compressed format that not only ensures that the browser will download it rather than display it but which also makes the download as small as possible.
If the W3C standards are for the browser writers then what standards should be used by those people who are actually writing web pages?
In HTML a million spaces in the source is exactly the same in so far as the final page as if there were only one space there. The only difference is that the more spaces in the file the longer the file will take to download. Now a few extra spaces isn’t going to make a noticeable difference to the download speed unless your visitor is on a really really slow connection. Some web pages may contain thousands of extra spaces beyond what is really needed though and that may be enough to make the difference for some of your visitors between waiting for the page to finish loading and leaving before it finishes. The other area where these spaces can make a difference is if your web hosting has a limited bandwidth or where you pay based on what you use. If a million visitors view a page where you have managed to remove just one space from the file then you have saved yourself 1Mb of bandwidth.

Those domains that end with a two character code are country specific while those that have a top level domain of between three and six characters are international. When you are targetting your pages just to people in a specific country then it makes sense to use the top level domain for that country. Depending on which country it is you may then find that there may or may not be a second level domain structure established within that country. Most of the larger countries have a second level structure like this (the most obvious exception being .us sunce the majority of Americans seem to prefer targetting an international market rather than a local one).
The .au top level domain belongs to Australia and there are only a small number of second level domains for use for targetting your site at Australians. This article lists those that exist and also identifies the criteria that you need to meet to obtain a domain within each of the SLDs.
Not all program updates are improvements. There have been a couple of occasions where I have installed a program update only to find that one of the features I got the program for in the first place no longer works.
Word Processing programs have come a long way sinced the early days and modern word processors such as Microsoft Word contain features that used to only be found in Desktop Publishing programs. Character spacing and Kerning is one of the options that Word supports, which will allow you to adjust the gap left between the various characters in your words.
