This paper conveys the outcomes of what results to be the first, though
initial, overview of commenting platforms and related 2.0 resources born within
and for the astrophysical community (from 2004 to 2016). Experiences were
added, mainly in the physics domain, for a total of 22 major items, including
four epijournals, and four supplementary resources, thus casting some light
onto an unexpected richness and consonance of endeavours. These experiences
rest almost entirely on the contents of the database ArXiv, which adds to its
merits that of potentially setting the grounds for web 2.0 resources, and
research behaviours, to be explored.
Most of the experiences retrieved are UK and US based, but the resulting
picture is international, as various European countries, China and Australia
have been actively involved.
Final remarks about creation patterns and outcome of these resources are
outlined. The results integrate the previous studies according to which the web
2.0 is presently of limited use for communication in astrophysics and vouch for
a role of researchers in the shaping of their own professional communication
tools that is greater than expected. Collaterally, some aspects of ArXiv s
recent pathway towards partial inclusion of web 2.0 features are touched upon.
Further investigation is hoped for.Comment: Journal article 16 page
