When I looked for blog system to use, I have looked to various systems. From big ones like Wordpress to small ones like NanoBlogger. At the end I ended with NanoBlogger, because it looked more suitable for my needs.
However I still needed some customizations to make it work exactly how I
want. First was to enable experimental titpe-based links. This makes
links look better and people (and search engines) can see from link what
is the entry about. Besides uncommenting some parts of code commented
experimental title-based links, there was needed little change to
archive generator to make correct links for previous/next entries.
Next think I wantes was RSS feed list for categories on main pages. This is needed as many people will be interested only in some parts of this blog. This part is a bit hacky and I choose simple way to do this by only changing parts in category links.
Last thing is listing which is included on other pages like pma.cihar.com. This part only uses existing code and doesn't really add anything new except two tempates for it.
Now I enjoy NanoBlogger and hopefully it will last some time :-). If you want to use same customization, patch is available here.
