There is no direct answer to this question.

If you think of it then it is a flamboyant style that usually would distinguish a leader from the team. However, at the same time flamboyance has to be complemented with actual knowledge of the technology/issues being addressed by the solution.

A few qualities that can make a good team lead:

1) Due diligence - A cliched term, but makes a lot of sense when one is leading a team of highly qualified technologists. Delving into the details of what each team member is involved in helps in constant monitoring of activities. It is a merry go round but is useful.

2) Reach the next level - communicate what the team is upto and what the achievements of the team have been to the next higher level. Gives visibility to the team as well as the lead

3) Personal outreach - common human beings (which means everyone except superman-m.h.r.i.p and Paris Hilton) are surrounded by pressures which can restrict thought flow at critical junctures. A good team lead can provide a reassuring pat on the back to team members who are under pressure. To do this you have to be able to identify with the team member and be able to give thoughtful advice (DO NOT discuss such issues with anyone - breaks the trust bond).

4) Encourage independent thinking - Reduces a lot of design and implementation problems.

5) Take the team out for a team-building session once in a while. Make sure the team gets "face time" with higher management. Invite higher management of course.
