mine comes and goes for no apparent reason (I was without votes for about a month at one point).
So I've given up flagging more than once a week and voting a more than a couple of times a day. Sadly all the older HN members I talked too say the same thing.
I wonder if the site algorithm is actually favoring newer / less active members?
I wonder if [HN spam filtering] could filter spam-tagged items out of the new page.
It already happens, I'm quite sure. Every time I visit HN, I first visit the main page, and then visit the new page. I mostly only flag egregious spam. I see some of that disappear as I flag it.
After edit: pg in the child comment below corrected me to point out that the noobstories view now does have flag links, and I can see them now as I follow the link.
These days there is too much spam to make the "new" page work.
