If you have actually found this post, CONGRATULATIONS!! The 'News Feed' and 'Latest Activity' pages stopped working late Friday evening and that means notifications are also not going out. Just before these pages stopped working, I actually received some duplicate notifications from some time back, so all is not well at the moment.
For now, if you are trying to find out if anyone has responded to your post or question, you'll just have to open your post or question and check, by clicking on 'Questions' or 'Posts' in the purple menu bar 
. Check the bottom line (the grey text) of each entry for when the last activity occurred. You'll then have to scan the post/question replies for the most recent 'last activity', which will again be in grey but at the top right of each reply.
I've reported the problem and I expect everything will be working properly by mid Monday.
Also a reminder that any private posts or questions will not appear in the 'News Feed' and 'Latest Activity' pages even when they are working as intended, so please remember to check if anyone has submitted an item marked as private since you last visited our community. Private posts and questions should be visible early next year in the 'News Feed' and 'Latest Activity' pages after HU release an upgrade that properly integrates these private submissions with the website. The current situation is a temporary work around that was quickly implemented to protect sensitive discussions and I notice that it is getting plenty of use, with over half of the recent posts and questions being submitted viewable only by our community.
Thank you for your patience,
Neil
The accompanying photo shows a Noisy Miner honeyeater taking a rest from aggravating other birds and doesn't look all that impressed with the situation either. This Australian native is smaller than a pigeon, but will take on much much larger birds than itself, continually swooping on and harassing other birds to defend its territory. As Wikipedia says: "The Noisy Miner is a notably aggressive bird, and chasing, pecking, fighting, scolding, and mobbing occur throughout the day, targeted at both intruders and colony members." en.wikipedia.org/wiki/Noisy...
