Yup - I know exactly what you mean. IMO - that's way too messy.
Perfect example:

When there's a new item to add to this, I will edit it and put it in is proper place - then add a new post stating there was an update. As you can see the last 2 adds where just tacked on to the end - that can be easily missed because it's not with the others. I wasn't going to bother the Mods for edit.
If I had to quote this 1st post each time - it'd be a huge mess to read. Plus - way too big!!
