I went through several phases.
1. I hated it. I couldn't figure out how to work it. Why change something that works perfectly well?
2. I accepted it, although I could not get back to my feed easily. Annoyin, but I could live with it.
3. I like it now that I found out I could get back to my feed by clicking on the word Hubpages in the header. I don't remember clearly what the old header looked like; but, the current one seems to allow more screen space for reading.
Did I miss the announcement? That happens to me sometimes.
