ShareThis draws its nearest audiences from a notably mixed cluster — Professionals, TV Shows, and Tech Personalities — with no single neighbor pulling far ahead of the rest.

The shape is flat: the top 10 scores span just 0.90 to 0.88, a narrow band with no dominant anchor. Aaron Lee leads at 0.90, followed closely by Roger James Hamilton at 0.90 — both Professionals within Celebrities and Influencers. The Last Word (0.90) and The ReidOut (0.89) are TV Shows, representing a second thread running through the cluster. Top Brass Bloody Martini (0.88), an Alcohol brand, and Bobby Umar (0.88), another Professional, round out the six closest neighbors. Joel Comm (0.88) and Sean Gardner (0.87) are both Tech Personalities — the only subcategory that overlaps with ShareThis's own Tools and Resources category in spirit, though neither shares its exact subcategory. WordPress.com (0.88) is the lone Technology brand in the top 10, and the American Jewish Committee (0.88) is the lone Non-Profit. Tallying the top 10: four Professionals, two TV Shows, two Tech Personalities, one Technology brand, one Non-Profit — no single subcategory commands the cluster.

ShareThis's audience shape is genuinely diffuse, overlapping with professional influencers, cable news programming, and tech figures in roughly equal measure rather than clustering tightly around any one kind.
