Can a plugin differentiate syndication feeds from actual site views?

You can use the template tag is_feed() to determine if the current request is for a feed:

if ( is_feed() ) {
    // It's a feed!
} else {
    // Regular 'ol WordPress
}

Note you’ll need to use the function after the request has been parsed (i.e. on or after the parse_query hook).
