I am cautiously optimistic. As
@Indos says above, in the 1990s they were just coming out of Madrassahs and brought a lot of extremism along; they had a Messianic Zeal then! BUT they are also human being, capable of change and 20 years in the wilderness, especially in such a connected, informed world, had to have some moderating affect on them.
Related to this topic, saw a video from within last 24 hours featuring Pakistani journalism Saleem Safi. He is one of those journalists from Pakistan whose opinion about events in Afghanistan are extremely insightful and informed-- HE is the one who should have been consulted by Americans instead of a lot of idiots in London or Washington DC commenting about Afghanistan.
Anyway, here is my understanding of Mr. Safi's key points (some points added per other sources):
1) Taliban have shown mercy and respect even to the Gov. of Kandahar who had killed a lot of Taliban.
2) So far, not enforced beards on men where in the past even the length of the beards were enforced.
3) Women are NOT expected to wear a Burqah--a head-covering would suffice.
4) Women are supposed to be allowed to go to work without a male escort.
5) Education for women through even PhD would be okay but in technical fields (Ex: Lady doctors)
6) Taliban are seeking legitimacy and they are not the same as they were (this was said by a staffer from the UK's Ministry of Defense!)
7) Taliban have not touched the Shia Hazara community so far this time--perhaps as an olive branch to Iran or as genuine change of heart.
8) Internal dialogs from Taliban revealed that they would have even spared General Dostum.
It is too early to say whether how many of these would be actually allowed but I am cautiously optimistic. Also, one thing to note is that beyond Kabul and very few large cities' whose very small more 'liberal' populations, most Afghans are very conservative anyway.
