A bliki is a combination of the two concepts (and words) blog and wiki. In the case of Simia this means that I try to run a blog on (semantic) wiki software. Since it is also semantic, I probably would have to call this software a sembliki? (just sbliki, or rather spliki is already reserved for a spam bliki, in continuation of the term sblog or splog)
Note that due to the history of the word, the web contributes only one latter to a bliki, as does the log, whereas wikis contribute three. I guess this means approximately nothing.
