The problem with rdfs:seeAlso is that no semantics are preserved. It is just a URL. - what content type is it? - what language? - what format? - what relationship type? rdfs:seeAlso is useless if you need semantics. If is essentialy a synonym for <a href="">
Within FOAF, the main convention is to use rdfs:seeAlso specifically to point to another foaf file associated with the foaf:person it's embedded in. This is a use that doesn't seem to appear in mod_link. I also think it's exceptionally powerful for discovery during the early stages of a new standard because it encourages scuttering round a web of instances of that standard. It's basically someone saying here's my file and here are pointers to other files of the same type I think you ought to look at.
To some extent, even though it's just an <a href> with no additional metadata, you only have to go through the link to find out what it's pointing at. But I take the point that you wouldn't know whether to do this without the additional data.
If this was done in RSS, we probably wouldn't want to clutter a feed with loads of links. So perhaps the convention would be to point at an OPML or OCS blogroll of RSS feeds.
