Mastering Pretty Permalinks in WordPress

Mastering Pretty Permalinks in WordPress: "using pretty permalinks, you need to recall the names of your pages hierarchy. Some like this style. I have come to like it for the past year. Some argue that it bloats that database. Others says pretty permalinks are great for search engine optimization. However, I think of it as a personal choice. I kind of like the ability to see the title of my post or page in the URL.
What do you use for your site structure while using WordPress (for those who do use it)? Have you had issues with the pretty permalinks technique?"
