The quality recruiters do so. I personally just get swamped and neglect sending out updates. Many times candidates are also applying for several roles and may not follow up on their own. I think the worst blunder is when a candidate desires feedback and gets only silence. Note that people, in general, hate delivering bad news "You were too weak on core Java / bad breath" and so avoid the conversation. The recruiters in the field for several years (5+) sometimes place a candidate 2-3 x in new positions. Recruiters keep up with the rock-star talent, which is always in high demand. It gets difficult to remember who does / is what if they are middle/average when burning through 200 profiles a day or 50 calls / day. Though I tend to do 50 / 10 for quality head hunting.
