I agree, the popularity of QRZ.com is amazing. Even those who do not use it, or the internet, know of its existence. As to, 'could I live without it'. Yes, I could. I dont have my rig hooked up to my computer, indeed, there is no computer in the shack, so I just keep a paper log next to the rig. Later in the day, or maybe a few days later, I enter my contacts into HRD. Sure, Its a big help auto-loading the fields. But do I need all that data? What do I use that data for? I 'think' I need all the data that qrz provides, but the reality is, I don't. I use the data to generate a qso map via the HRD system to display on my own web site, and on my profile, here, at qrz.com. When you have a certain number of qsos, the map looks jumbled, and meaningless. Of course, I can use google earth to provide a scalable presentation, but is it useful? Again, it can all start looking overloaded with too much information. I use the data to show friends, neighbours who have a curiosity about amateur radio, so my maps must be clear, not overloaded. So for me, the usefulness with all this data is limited. It is all to do with what you use the data for. I don't contest, I just like the odd ragchew and chase DX, so other users of the qrz.com service will have vastly differing requirements. Yes you are correct, it is a major convienience, but for me, not a necessity. The paper logs still have all the essentials I really need. Wondering if others could pitch in with how they use qrz.com. I genuinely find this a fascinating topic.
