Hi @glenalbrethsen.
I've been over there for a little over a week now. I don't see many there from my circles, so when I was saying claim it is under the assumption that many like myself haven't been over there, or aware they even had a drop and could access it with the keys they use here.
In 6-12 weeks the chain is migrating to a different chain, called Cosmos. There will be an airdrop, although the supply may change. If it does, the airdrop will be equal in percentage to the amount one holds now. When this happens, you will need to be active there in the sense of seeing the announcement and then claiming your new account/drop somehow using your Blurt account. If you miss out during that time frame, you miss your airdrop. This is due to it not using the same chain, I'm guessing. None of the current posts will be migrated, just as they didn't migrate the posts from Steem as they did here.
I've suggested that they keep Blurt going as well, and they seem open to the idea. I'm astonished at how much they listen to the community there. However, it does seem likely that at some point (or from the beginning) they will drop support for Blurt. Despite my suggesting they keep it (which aligns with their philosophy of multiple projects/airdrops which is intriguing to me), it seems logical at some point for them to drop it as it just doesn't make sense to run two different blogging platforms.
If/when they decide it's not logical (which could be right away) the Blurt you hold now will be worthless. So if you want to hold onto the coins in a sense, you will need to be active enough to claim the drop. Or, if not, you will want to begin cashing them out now so you're not left holding worthless coins.
Sorry I didn't explain better in the post itself. I was assuming most here have never gone there at all, and regardless of whether you want to leave the opportunity open by getting the new airdrop, or cash them out now for something else, the window is closing to do so. :)
Hope all has been well with you.
