'Networking events', are completely the wrong way to network, in my opinion.
Rather than saying the event is wrong, I would say it is the way many people network.
Over the years I have seen some really disasterous networkers. They usually fall into one of three categories:
- Expect to get work instantly
- Try to "work the room"
- Rude and aggressive
At a recent event, I heard a lady say to a website designer "
Stop trying to sell to me!"
Some particularly "memorable" networkers included:
A female accountant staggering around the event, telling everyone how drunk she was, and then asking people to give her access to their customer/client details so she could contact them about her service
.
A Financial Advisor at a BNI chapter spent almost his whole 10 minute presentation telling "near the knuckle" and beyond jokes (even about beastiality)

A female photographer undressed until she was down to her bra and panties - to promote her "boudair photography". (Even if she
had had the figure for it, it really wasn't appropriate while we were eating breakfast). To top it all even after her presentation she didn't leave any business cards - expecting people to remember her. We did, but not necessarily for the right reasons.
When done correctly, networking, whether at formal/informal events or groups, can lead to so much work that you don't need to advertise (apart from the annual subscription I pay to have a link in my signature on UKBF, I've never needed to do
any paid advertising). If done really well, you can get new work even when not at "networking events" (I picked up a new client at Remembrance Day comemorations - no I hadn't set out to do this).
When I started on the networking circuit, like many people I tried to
sell to the other members in the group, event or whatever. Now I let them
buy! There's a huge difference
