If you are just hosting your resume on the site then you probably won't get much benefit from the site. Instead you should use the site to showcase some of the work you have done in the past like projects, design portfolios (if you are in that side of work), code etc. You can also post articles / posts etc to showcase your expertise & knowledge.

I do that on my site along with a blog and I have had great feedback about it from employers in the past.

Yes, because when recruiters ask for your resume, just give them the link. They can view it immediately, print to PDF if they want a copy (warning: cross browser "Print to PDF" functionality can be flaky), or print a hard copy. I don't have to perform a file upload.

Most people will read your resume anyways, even if you have a LinkedIn. My LinkedIn lists all of my positions; my resume is a smaller subset of skills & experience I market myself as.

What do you want to do that you cannot do with Linkedin?

Get attention of the recruiter and Stand-out from Rest of the crowd

unless it had a portfolio of some kind(code or design, etc) I would think it's marginal. You could have a contact form for privacy concerns.

Precisely, I could showcase many things with a better UX. However, I am assuming recruiter either will feel lazy or just not care to fill-out a form to get my contact info.
