I do not agree on this. I am migrating to hubspot and I will have to , work on the data to identify each particular tag is map to a particular field (column in the excel), then create 30 custom fields which will be populated with 0s and 1s and then import.
This is alot of work!
Also it will put a more pressure on the DB.
I think tags is a must functionality that HUBSPOT need to implement as soon as possible.
