>      note: I would not make a link to each "like" directly part of one's foaf (one relation per like). If we put all our info in our foaf then we will have huge foaf file. Better think of likes as a very specialised feed. One could have a blog of one's "likes": ie a feed of things one likes, dislikes, etc.... These would be very similar in a way to microblogs such as twitter.
>   "Like", bookmarks, and microblogs:
>   In fact a "like" is not that different from a bookmark, which is why the idea of a bookmarklet seems so natural: identi.ca and faviki have their bookmarklets. In turn a tweet is not that different from the above: it is represented as an Atom Entry (or used to be). So one can think of a "like" as a special type of atom entry/SIOC post. 
> So in that case the question then becomes: what gets pinged? Sindice? DataSpaces? Faviki? deli.cio.us? Well once one writes a blog one can ping anything. But we were mostly interested in pinging the writer of the blog to show our support for his post, though he in turn is going to be more please if this ping also pings your friend network, as that gets him more readers.
>     So given the above reasoning we can in fact see that the "like" buttons already exist on the blogosphere today. We have both comment mechanisms, pingbacks and bookmarking services. So all that foaf+ssl adds, is make the commenting authentication much simpler, more reliable and allow the author to more easily connect with the pinger.

It is a major part of the FB experience, and in Twitter land one has the same with RT. This lack of intentional feedback, makes blogs a lot less personal than they need be.
>> Adding it to blogs would be really simple. A foaf+ssl enabled like button, could allow one to authentify oneself in one easy click. The blog post could then simply add a like relation to the user's WebId to the RSS feed. This could of course also be used for comments. A good blog engine could then parse the foaf and use the information gleaned there to produce a profile of the liking person: what blogs he had (verified if the blog points back to the webid), what SN he is on, etc.... 
>> Currently it would require leaving a comment with an easily falsifiable email address. Asking people to authentify via email would be cumbersome for something as easy as liking something.

I see Annotations as Bookmarks with benefits. I also see enhanced 
Bookmarks++ as expressible in structured form via triples. The act of 
pinging should result in:

1. Statements (triples) in the Data Space (a collection Named Graphs at 
a location on a Network) of the Pinger
2. A ping notice sent to the Pingee
3. Pingee generating Statements (optionally) in his/her Data Space.

All of these statement ultimately add density to public, private, and 
semi-private (ACL controlled) Linked Data Spaces. Basically, we simply 
accelerate the self-annotation aspect of the Web of Linked Data, by 
embracing and extending a broadly used interaction i.e., pinger URLs.

The data created from these activities doesn't need to be in a FOAF 
document, it simply needs to be de-referencable via WebIDs associated 
with a FOAF profile. This is basically where SIOC comes into play since 
it actually models Data Spaces (which goes beyond the initial goal of 
online forums modeling).

In ODS you have SIOC based Data Spaces (which have their own URIs) for a 
myriad of data item collections: Calendars, Blogs, Discussions, 
Bookmarks, Feeds, Bookmarks etc., each is associated with your ODS 
generated WebID.
