Neo template, the one being used in this blog and several others, shows the list of recent posts or the list of posts under a particular label in the middle column. The original version of Neo did not have any Older/Newer navigation links for this list and showed all the posts under a label at once. This results in an insanely long list if you have lot of posts and there was a limit of 100 posts too (the limit imposed by Blogger feeds). Some of those who bought Neo felt that it is important to support navigation and break the 100 post limit. I couldn't think of an easy way to do this and so I didn't attempt it for a long time.
Just recently I came to know about the start-index parameter that can be applied to feeds to specify which post the feed should start with. This parameter combined with max-results control was all I needed for navigation. I have implemented navigation in this blog using this method (it's been there for a few days now). If you have bought Neo and are interested in this feature, I can upgrade your template if you download and send me your current template in email.
In other news, Blogger hack search engine has served about 500 search requests within a few days of it going on air! People seem to find it useful to avoid going through irrelevant search results and find what they want quickly. My part in this effort was very small (just adding the list of hack blogs). We all should thank Google for allowing customizations on it's powerful search engine. A big "Thank you" to all those brainy folks in Mountain view :)
