It's best to simply archive talk pages. It only takes a minute and it's quite effective at recording all previous conversations. Archived talk pages look like this.

Edit summaries are nice, but as JPhil says it's quite easy to manually examine changes. I try to always leave a summary when I edit someone else's page, though.

I agree whole-heartedly that the Delete Template should always be accompanied by  a valid explanation. Leaving it blank only inspires confusion. Reasoning should never be left "implied".
