Google Insights Suggests Minimize twitter.png

Google Insights is suggesting:

Losslessly compressing http://openconcept.ca/…contrib/service_links/images/twitter.png could save 611B (51% reduction).

If these are compressed with https://tinypng.com we can save 37% or 2 KB in total if we look at all of the images in this project.

The energy, bandwidth & time which is wasted (even little bit at a time) can be fixed pretty easily.

This likely won't have a huge impact on the performance of any individual site, but it's pretty huge when you look at the nearly 40k sites that are using it.
