Please avoid adding these icons within the prose of articles: per Wikipedia's Manual of Style for icons, "Icons should not be used in the article body... This breaks up the continuity of the text, distracting the reader".
In addition, icons used in this way are primarily decorative, e.g. "aesthetics are in the eye of the beholder: one reader's harmless decoration may be another reader's distraction": While the icons provide visual cues in certain circumstances, writing in prose will usually suffice. Instead, provide a link to the services directly.
