I am adding some new features tonight to the ever-expanding Blong! blog search engine (that doesn't really index anything at the moment).
I have added Sphider recently and it needs a lot of work before it will be functional within Blong!
I am adding the Comments module tonight - make sure you comment on your blog and any other that you find that may be interesting to others (or not).
Anything else you would like to see added? Let me know and if it fits, it will wear it!
Edit: I am having a bit of trouble with the Comments module - if you are using Blong! (and I know some people are) please bare with me as I try to fix this up!
