I recently started using LinkedIn to reconnect with former co-workers from the past decade. Most of my initial connection requests were accepted, and I had some pleasant but brief conversations, even with a few people in high positions who didn't have to respond but did. However, I also reached out to colleagues from over 15 years ago, sending out 10 requests to people I once considered friends. Unfortunately, I received no responses, except from a former boss, which was surprising. I enjoyed working with these individuals, and I wonder if they see my profile and think I'm only reaching out because I need something. The truth is, I'm not looking for their help; I genuinely wanted to catch up. This experience has made me question whether it's best to leave the past behind. A friend of mine recently advised against using LinkedIn, saying that former co-workers aren't really friends and likely don't care about my current situation. Maybe he has a point.
