Meetings, meetings

In the 21st century isn't it about time we came up with something to replace the endless and pointless meeting to which we all go. Why do I have to travel 50+ into work to sit in an over or under heated room (depending upon whether it is summer or winter) with only half of the people who should be there to attend "a meeting". I have lost count of the number of meeting that I have turned up for that have been cancelled at the last minute because too many people sent apologies. Why do we have to have "team meetings" it's not for team building purposes because, generally, half to two-thirds of the team are missing and it can't be for communication purposes because, well....half to two-thirds of the team are missing. If something is vital for everyone to know - send an e-mail, or a text, or tweet about it. If you want more people to attend - hold your meeting in cyber-space via Skype. If I hold a meeting, it has a clear purpose, stated aims, a proposed outcome,  an agenda - to which we stick- and is targeted at the people who will help to make those aims a reality. Does it make me naive to if I wish that al meetings could be like that?
I now have two goals for meeting attedence;
1. The pupose of the mmeting, and my contrubution must be clear to me from the moment the invite to attend reaches me.
2. The meeting should not be higher that then first floor of any building.

Actually, the last point has little to do with the effectiveness or otherwise of meetings and more to do with my lack of desire to slog up more than one flight of stairs for anybody!.
If anyone wants to discuss this further, contact me with some diary dates and we'll set up a meeting
