Looks good at first (simple and clean)
however, I came across a number of issues :
- database tables were created with the wrong prefix
- various scripting errors (they were reported on the authors website)
- very little to no documentation (e.g. how to set it up and start using it)

because it looks good, I hope to see a more "ready" version soon, for now, I will have to uninstall it, and I've to go out and look for another (stable) blog component for J1.5

but it seems to be more of a wrapper component.

it only includes blog or entries from that network, although you may be able to tie a "book" to your site, it all seems to be managed, stored, ... on their site

it looks good, if that is what you want to include

BUT : I strongly suggest to include that in the description, as it may be an unpleasant surprise for some people. As this touches the thin lines around privacy and security

e.g. sites which have disclaimers on what they do with the data of their registered users, have no control on what iBook will do with their registration information.

I was looking for a stats component for Joomla 1.5 (in native mode)
I came across this one and liked it at first sight.

I didn't need the full blown detailed vistitor analysis (as I'm using Google Analytics for that) just a component, I could publish to the front end.

up to now, this seems to do it well ... it is :
- light
- quick and easy to setup (took me about 3 minutes)
- and clear numbers

to the developer :

1 big downside, it renders my site XHTML invalid :( using the http://validator.w3.org ... before I install this component, my site is 100% clean and valid, after installing, 95 errors :(
hopefully you can do something about that

I would still recommend this to anyone looking for a light, good and simple stats component
