Are the user rss feeds not available any longer?

I just realised that the RSS icon in firefox disappeared and my feed in Google Reader does not display an update made today.

Is it

1. just a bug?
2. a feature that has disappeared intentionally with the last update?
3. that I have a problem seeing orange coloured items?

I hope for (1)

[Update:] Google Reader and thus the news section of my web site via feedburner now has got my recent posting - the most important part for me. Still no RSS icon
