This is great! I just discovered that my blogs' Google PageRanks have gone up: Techqi (this blog, ahem) now has a PR of 3, and AV Scan, which I discontinued due to insufficient viruses, made me happier - it now has a PR of 4! I used to think PR increases in general with time and decreases for inactive sites, but apparently there's more than meets the eye.
In addition, some of my (edit October 10: alas, relegated to page 2!) posts are still on the first page (and even on the top spot) of Google's search results for certain keywords. I'm blogging for about two years now and I'm really encouraged by all this. The quality of your posts still counts, it seems.
