Great potential that I want to recommend but a disappointment in UK practice.
Look at the number of foul-mouthed people trolling INTERNET and you must expect some foul-mouthed, weirdoes. They just want to make others feel how they feel as rejected social dregs. Give them a hug. If they don't change - tell them where to go.
There was a time when Meetup.com told you all people in your area interested in the same topic or activity as you. For some reason Meetup, stopped giving that information. Why? Feel a con coming?
Now Meetup.com tells you there are 64 people near you interested in the same topic. What does 'interested' mean? Something vaguely similar.
What does 'near' mean? Up to 100 miles.
Now either Meetup.com are out to con all new organisers or they are just plain dumb. They are Americans. From the other side of the Atlantic, they look at a map and see that Dover is near London. But Dover is up to three hours by public transport and a near 2 hour car journey that few in the UK would undertake lightly. And not for a regular social event.
What started as a great idea with potential is now degenerating into a con. Let me plaguerise Boomtown Rats: Its a rat trap - don't be conned!
