On the other hand we do have a bit of an addiction to PowerPoint; to images of holes in the ground; of random artefacts; and occasionally of insanely stereotypical 'reconstruction' drawings.
Other sites such as Wordle and Tagul enable anyone to analyze and present text in a visual way. They work by scanning text (from my MA thesis in the case of Wordle and Seandálaíocht in the case of Tagul) and isolating frequently used terms which then appear bigger, the terms then acting as links in the case of Tagul (try clicking on the image below).
Finally, a little rant: why the hell do archaeologists (and I include myself in this) design/commision websites that are useful only to other archaeologists? Sites like excavations.ie, archaeology.ie, the ADS etc etc are just not accessible to the general public. We need to write/design sites that engage, that inform and that convey complex information in a simple way. While it may sound childish; bright colours and simple shapes may be the best tools for doing it.
