Sounds about right. I currently hold several .info and a couple of .biz
names, but mainly because I have most of them in the .com and/or .net
version as well. And I registered them just to avoid someone with cruel
intentions doing it first. I've yet to see someone actually using any
of them to reach any websites linked to them (if any). With the
exception of a .info domain I registered to use with a Norwegian IRC
help channel for PHP programmers (which generally just contains the
channel rules, starter links and a self-made pastebin).
Just as a contra-indication, my experience is that .info is becoming
increasingly more popular and I've got several that I deal with - both
my own and those of other people (my second most popular website is on
a .info domain). The big advantage of .info, at least for English
speakers, is that it's a real word (or, at least, a common abbreviated
word) which can make the entire domain make sense as a phrase. From
here in the UK, it's often also a better choice for non-profit sites
than either .org or .org.uk, as it's easy for people to get confused
between the gTLD and ccTLD forms and end up at the wrong place. And,
according to published stats, registrations in .info are growing
faster than any other gTLD, even though it's still running in fourth
place overall behind .com, .net and .org.
I'd agree, though, that no-one seems to want .biz. I don't know anyone
who uses it for a primary domain, and only a handful of owners who've
registered it defensively and pointed it to an existing domain. Part
of the problem is reputaion - all that seems to be on .biz are
spammers and scammers.
