I recently developed a site for city gardeners (link in my sig), and have been happily pootling along with 30 or so new visitors a day, which is great. However, a week or so ago, I could see in the stats that I had been linked to by someone on www.stumbleupon.com, which again, was great. Now, suddenly I get 350-400 new visitors a day! This is also great, but I will have to start thinking about upgrading the hosting if it continues. So, I have two questions. 1. Is this Stumble Upon thing a good thing? And if it says I've had 300 or so visitors in my stats yesterday from them, is that true? All I can find on the site is that two people have listed me as a good site, and the only link back from my stats is a referral page - http://www.stumbleupon.com/refer.html, that is obviously masking where the clicks have come from. 2. Has anyone here been listed on the site, and if so, will the visitor numbers drop, or will it continue at this level? Are sites listed at the top of a list and then drop down the list, or is this likely to carry on? Obviously I'm chuffed to bits that I'm getting so many visitors and that the word's getting out, but it seems strange suddenly have so many hits, and to come from one place like this that I've never heard of before. Please help to quell my paranoia! Thanks.
