You can't do this in the space's content tab other than scrolling through and looking for the content items with the most likes. What you'll have to do is use an alternative site search engine SCN has and then sort the content by likes.
- Go to http://scn.sap.com/search.jspa
- Search for sap (there's no search wildcard available but "sap" appears on just about all SCN content, so does "a")
- Then select Sort by = Likes
- Other filters:
- The default is anytime (all time) but you can narrow this down to past day, week, month or year. However, the total number of all time likes will always be displayed!
- Search withing specific spaces ("Restrict to a Group or Space:") and content type ("What:")
- You can also sort by ratings
For examples, here's a query for the most likes blog posts in About SCN over the past month: http://scn.sap.com/search.jspa?view=content&resultTypes=blogpost&dateRange=last30days&q=sap&rankBy=likes&contentType=blo…
