Is meta tag injection good practice?

[MrMaz]

Right now Links injects a meta description tag directly into the header. Not sure if this is the best approach or not?

It is fine to me but I have one suggestion.

If the Link content is too long, the meta description might display badly. How about add an option to limit the excerpt length while there is already full link content length? In this way, the meta description is only show excerpt.
