While not implementing these buttons is of course an option, the push from search engines to promote retweeted links, likes & +1-ed pages of friends in their search results could harm your competitive position.
For DirectLyrics I recently created a one-stop solution which solves all the issues these buttons cause. Key issues that needed solving: quick & fast loads (2kb gzipped), wide provider support (5), and non-blocking.
- Easy install on any page by including an iframe which refers to a CDN hosted, long term cached html file.
- Control variables on layout, supported providers, relevant url. Passed as #hash (keeps the file completely cached for users).
- Support both (native) tall counters as well the wide layout including the counters.
- Providers: Facebook (Link and Send), Twitter, LinkedIn, StumbleUpon and Google +1.
