Yup, totally amazed me when I heard that's something people I know do regularly, because if I want to go to a site I type it in the address bar and save myself a click, but like I said, "Normal people don't think like us..."
I must admit I do that too. It's quicker, if I want amazon it's easier to type that into the search box (my start page), it auto suggests so I only have to type a few letters and then click, I think alot of people prefer to click more than type - one hand always stays on the mouse and you don't want to type in a url or even '.com' with one hand.
Back to serp changes - my niche has been stable for a week now and my recovery has held. It's strange but my recovery seemed to start earlier than everyone else's - around the 9th / 10th. Which makes me think I had some kind of timed penalty which just happened to coincide with Panda.
Tbh though I'm not feeling good about this whole thing, I expect to drop out at any moment. I think once you've dropped down it's very hard to trust that you'll keep the rankings. I still feel very nervous about investing in the site (time or money) and will probably feel the same for at least 6 months.
