Re writing dynamic urls not needed say google

Well you learn something new every day. I have spent the last 2 hours looking for the best way to rewrite the urls of this blog with .htaccess Just as I had it figured out I came accross the official google webmaster central blog. According the the bofs at big G dynamic url's if kept simple with relevant strings then they should be kept in tact. You will notice the link on single post pages on our blog end with .co.uk/blog.php?id=2. Well today a read the following "The reason using dynamic URLs is probably preferable is because Google can do some basic analysis to work out whether or not it's a useful or non-useful variable, specifically based on the fact that it's a variable. For example, if it sees ?pageid=1, it could theoretically also try ?pageid=2, and ?pageid=3 of its own accord. If those bring up new content, the bot knows those are useful variables and should be considered as such. If they bring up duplicate content, it knows those variables are non-useful from an indexing perspective"
