There are two dirty little secrets, possibly more, with 23andMe. First, there is a limit of 2,000 matches unless they changed it. It used to be 1,000 matches. However, as long as you send out sharing invitations (called Add Connection now), those used not to count against the 2,000 limit. Not sure now as I haven’t heard of it changing. What happened in the past is the minimum centiMorgan (cM) / percentage threshold would rise over time.
The biggest other dirty little secret is you don’t automatically share with all your matches. I am not talking about those who opted-out of sharing. If you or they don’t opt-in for sharing, you may see a match, but one of you will need to send the other Add Connection which will have to be accepted. I do a short intro message that I copy/paste as sending it to hundreds of people is a pain. I will add a short note if I see we share a location connection. I sort by Newest Matches to make it easier to figure out if I need to send connection requests.
The bad news is sometimes you see a potential match, but they don’t accept sharing. I star (star) those so I won’t waste time later trying to send them an invite. I also star those close family members. If you see Connected or Invitation Sent, then you don’t need to do anything. I went through almost 300 Add Connections last night and have a lot more to do later.
It would be nice if there were an easier way to send connection requests instead of having to send each one. I would recommend staying on top of them as the sheer number can spiral out of control fast. I hadn’t sent any invitations in a while and it looks like I may have several hundred more to go, possibly a lot more.
I noticed that I can download the CSV file which will show me who I am not saying with. This may make it easier.
