Dolls & robots 
As the article stands right now, the lede has absolutely no mention of dolls or robots.  The entire article doesn't contain a single mention of the word 'robot'.  I have made persistent efforts (most recent) toward rectifying this, but each time my edits have been reverted.  Rationale for the removal included the view that I was adding original research and that my additions were not WP:LEDE compliant in that there was no mention of robots within the body of the article.  For editors who strive to increase the quality of Wikipedia, it is clear to me that the most helpful action to take for these valid criticisms, instead of simply hitting the 'revert' button, is this:

- Statement in lede is unsupported.
Fix:  Flag as needing a reference.  (I found a great book with a single googling.)

- Lede is discussing a topic that is not discussed in the article's body.
Fix:  Add a statement or two into the body.

I realize that these approaches to fixes require putting in a little more effort, but that's the direction that leads to higher quality articles instead of preserving the gaping holes in them.

Last point:  If there's an edit instability regarding the quality of an article, it is clear to me that the best place to initiate a Talk discussion is on the article's Talk page and not any particular User's Talk page (ie: mine).  This way other editors who care about the issue in question are not required to go hunting around in order to get up to speed on whatever disagreements had transpired.  Now if the issue is that a particular user is vandalizing an article, then that would be an excellent reason to open a discussion on the UserTalk page and keep the article Talk insulated from irrelevant noise.
