Over the past few years, I’ve become a fairly devoted fan of WordPress — it works well, it’s so easy to set up I could practically do it in my sleep, and it’s free as in speech and as in beer.
But, I also like to check out the competition. A few weeks ago, I spent some time using Serendipity, another PHP-based CMS that is very easy to use. As an added bonus, Serendipity supports PostgreSQL and SQLite out of the box, so if you don’t have MySQL installed and/or would prefer to use PostgreSQL or SQLite, it’s a great option.
Overall, I liked Serendipity quite a bit — I’m not ready to switch, but it has some really good features. I’ve got a review up on NewsForge, please have a read and give Serendipity a shot if you’re looking for a good CMS or blogging software.
