I talked to prototypejs' maintainer and he would offer prototypejs for
adoption as he does not have enough time for maintenance nowadays.
Updating prototypejs  and fixing bugs would be really useful and
would allow tt-rss to be back-ported to wheezy-backports. 
next maintainer, this is why I'm sending this email instead of taking
over the package.
Is anyone interested in helping out tt-rss through maintaining prototypejs?
