My Website 'sucks'

Recently, one of my student's whose honesty I value, told me that my website 'sucks'.

I don't really disagree, my website needs a lot of work, and I've been trying to improve it, but his use of the very popular word 'sucks' is one that repels me.

It seems everywhere I turn I hear "that sucks".

In my younger years, we used to say "that stinks" or "that's a shame". Today it seems to be "that sucks" or "it sucks to me you".

I was inspired this morning to check out its definition today at Dictionary.com. Here's what it says...

I'm not sure what definition is best for use with my website---the closest would seem to be the fourth intransitive verb form

Vulgar Slang To be disgustingly disagreeable or offensive

I'm not sure that my website is disgustingly disagreeable or offensive--but it may very well 'stink'.
