From almost the beginning of my blogging career, I used mybloglog.com to keep an eye on real time stats. I liked it. It gave me a quick peek of how things were going and I could make adjustments if I was being hit hard by stumbleupon or if something screwed up and one of my sites was down for some reason. Recently, (and it is unfortunate because I just reupped 3 blogs for a total of $75.00) something has screwed up and I can't log in. It something to do with yahoo and mybloglog and the combination of passwords or something. I'm emailing support but I have my doubts...and since this is such a crucial time of year, I felt "naked" without my realtime stats. I use google analytics and awstats as well...but they aren't exactly realtime.
Anyway, I just signed up with mint at http://www.haveamint.com ...it is $30.00 for each domain but unlike mybloglog it installs on your server so you don't have to pay yearly. I only signed up 3 blogs to start, but I really like it! Great referrer info and great to see the search phrase activity ...a bajillion times better than mybloglog.
Another helpful stat program is crazy egg. http://www.crazyegg.com That program has taught me a few things as well ..and it is free ...can't argue with free!!
