Well, I know my posting has decreased a lot lately and I hadn't really noticed too much more than the normal "off questions" but there are going to happen and I find them pretty easy to spot and usually just ignore them after a few posts because by then they are
figured out. 
What I don't like is when someone posts a genuine question asking for honest advice and people jump on them rudely and treat them like they are stupid or ridiculous for asking the question.
I have seen that happen a lot lately and I think it is rude and intolerant. In my opinion the artificail insemination question was one of those. It was actually Yorkie Rose who mentioned the need for possible dilation to accomodate the penis while we all know that during labor the body transforms and stretches to accomodate and enlarge the birth canal so it wasn't a ridiculous or stupid question at all in my opinion.
Those who have owned yorkies for a while and have a lot of info about them and are members here should share their info willingly and KINDLY to others OVER and OVER again because there will always be newbies to the breed.
If they get irritated by the SAME questions over and over then stay in the subject areas you prefer and don't respond to the question because it is worse to be mean in the response than to not respond at all or out of irritation in my opinion. We lose good new members that way.
I know that I have only been on here for about 8 months but I have learned a lot in that time and I get sort of irritated with some of the boring subjects being raised over and over and some days I don't feel like responding at all, but other days when I feel like helping someone out and have the time, I will respond.
