Yes, but you will ultimately be better off using SPARQL to handle 
content-negotiation challenges. Simple example, you hear that Google is 
now very interested in JSON-LD, HTML+Microdata, and for legacy reasons 
HTML+RDFa. How do you respond? Your options:

1. Build a new parser for the latest structured data representation 
notation favored by Google
2. Add the above to the SPARQL query results formats supported by your 
SPARQL engine.

Examples:

[1] 
http://linkeddata.uriburner.com:8000/vapour?uri=http%3A%2F%2Fdbpedia.org%2Fresource%2FLinked_data&validateRDF=1&defaultResponse=dontmind&userAgent=http%3A%2F%2Flinkeddata.uriburner.com%3A8000%2Fvapour%23this 
-- Vapor report on a sample entity URI from DBpedia

[2] 
http://dbpedia.org/describe/?url=http%3A%2F%2Fdbpedia.org%2Fresource%2FLinked_data 
-- go to the page footer where different formats are listed, then lookup 
the URLs (you'll see that they are all SPARQL Protocol URLs)

[3] 
http://dbpedia.org/sparql?query=define%20sql%3Adescribe-mode%20%22LOD%22%20%20DESCRIBE%20%3Chttp%3A%2F%2Fdbpedia.org%2Fresource%2FLinked_data%3E&output=text%2Fhtml 
-- Take this otherwise ugly URL and paste it into Chrome (with a 
Microformats sniffer enabled) .

SPARQL is a powerful mechanism for extremely productive Linked Data 
deployment and exploitation. That said, it is still an option in regards 
to Linked Data construction, deployment, and exploitation.
