However, this is standard html practice by most companies as you will see if you go to almost any major site.
Here are some urls

In fact while I was looking for examples I didn't find any that used the & and the ones I found using just & were easy to find.
The "standards" committee,
www.w3.org/, recommend using the & but there are very few that follow that recommendation. There is also not a single major browser available that does not handle the "&" character correctly in a url and because of the volume of existing html on the web it is unlikely that they will change that in the near future because it would break most existing sites.
