It is growing rapidly. Since Haptics-e is a brand new journal, it's reputation is not yet established either way. Promotion committees are made up of people from outside one's own discipline, so they will not in general be impressed by the composition of the Governing Board and Editorial Board. The bottom line is that if you are seeking critical academic appointments and promotions at the beginning of your career, and you have only a handful of journal publications on your record, Haptics-e may be too risky. We are the first and so-far only journal devoted primarily or exclusively to Haptics research and technology.
Electronic publications have three potential vulnerabilities with respect to archival retention.
First, electronic distribution via the internet could fail. Second, the Haptics-e server may go down and loose data. We have a robust network and backup system in place. Finally, and most significantly, as time goes on, the .pdf file format will become obsolete, and somehow we will have to up-convert to whatever is new. There is a lot of research going on world wide on electronic document archiving.
