Abstract: The invention relates to systems and methods of identifying social media influencers and providing location-based alerts based on social media content items posted to social media providers from monitored locations. The system may identify a user who visited a specified location based on a social media content item posted by the user from the specified location. The system may provide an alert to an entity such as a retailer whenever the user re-posts from the specified location. The system may further determine whether, to what extent, and identity of users over whom the user has influence based on one or more influence factors. An influencer is a user who is determined to have influenced the behavior of other users, as determined from the user's social media activity and/or the influenced users' social media activity.

Abstract: A roll-forged drill bit 1 comprising a shank 3 for insertion in a chuck of a drill, the shank 3 including an helically twisted web 7 defining a cutting tip 9, the cutting tip 9 including a central chisel edge 11 and a cutting edge 15 defining the maximum diameter of the cutting tip 9, wherein the cutting tip 9 is formed after the shank 3 has been roll-forged and includes a pair of faces 13 defining the chisel edge 11 and a pair of upturned flats 17 defining the cutting edge 15. A roll-forged drill bit 1 according to the present invention provides a significant improvement in cutting speed over known prior art roll-forged drill bits.
