We are now used to seeing ads on web pages, and it seems quite normal. In fact, occasionally, they are even interesting or useful. And Google is certainly working hard to make them even more so.
Tom Wilson has published Information Research for many years ...
Information Research, is an open access, international, peer-reviewed, scholarly journal, dedicated to making accessible the results of research across a wide range of information-related disciplines. It is privately published and edited by Professor T.D. Wilson. It is hosted, and given technical support, by Lund University Libraries, Sweden. Editorial support is provided by the Swedish School of Library and Information Science, Gothenburg University and Högskolan i Borås. [Information Research: an international electronic journal.

I occasionally look at it. It has carried ads on issue contents pages for a little while. In the current issue the location of the ads has changed: they are level with the contents on the right hand side of the page.
For some reason, I find these very intrusive and inappropriate. I am not quite sure why. It may partly be to do with the contrast between the blues, but this only contributes to the uneasiness, it does not create it. And it is probably difficult to offer ads which are in line with the article contents. However, call me old-fashioned, but I guess my main concern is that the table of contents of a research journal doesn't seem like the place to view ads.
[Of course, I am not saying that Tom should not do this. He does a lot of work and has real costs.]
