He’ll get something of a list of titles and duties while there.  "Vice president of product development" will correspond directly to LiveJournal.  A release states that he’ll also work as the director of product development for SUP, which owns LiveJournal, and serve on SUP’s executive committee.

These sorts of thing should, to abandon (and/or mix) the fish metaphor, be right up Shellen’s alley; he used to manage business and product strategy for the creators of Blogger.  Then, following Google’s acquisition of Pyra Labs, he became the founding product manager of Google Reader.

LiveJournal has had an unusual number of ups and downs in the past year, with account suspensions and the sale to Russian SUP being two of the more important events.  It’ll be interesting to see if the addition of Shellen helps smooth out the operations in any way.
