One thing which I don't like about aggressive OSS supporters is that they leave no opportunity to badmouth Microsoft. Every blog post posts hatred and cons of Microsoft. It looks very petty. I often feel that some bloggers blog not to propagate open source but to vent out their anger at Microsoft. This looks so petty that no average person will consider open source seriously. For them, these OSS guys are 'just a bunch of frustrated fanboys'. MS never badmouths open-source communities, whereas some OSS users just live to badmouth MS.
And about OpenOffice, it is not comparable to MS office. MS office has a great deal of features.
Has anyone seen the way Praka decorates his posts with 'M$haft' or 'winblows'
Remember, every average user, unaware of open source, has a great subconscious feeling of respect to the software he uses, which happens to be a Microsoft product in majority of the cases. He is very happy and satisfied. And one day, he logs on to a forum on to find some people saying that 'Windows is crap'. He will never accept that 'Windows is crap' because Windows has been satisfying him. This is where he develops a defensive attitude towards the fanboys and so whatever these fanboys say will again be subconsciously 'rejected' by the average user. Along with, it also spoils the attitude of that user towards the open source communities. He perceives that open source communities are just a bunch of negative brain washers. There goes down the drain all your effort to propagate open source.
If a linux fanboy comes to me and gives me some Linux OS on a CD/DVD and says 'Windows is crap, try this Linux', I will break that CD/DVD into 2 pieces.
I am a proud, happy and satisfied Windows user. I have nothing against open source. The key reason to being satisfied with a software is that you should know that softwares too have their limitations. You should not expect the world from softwares.
If you guys want to really propagate open source, propagate it on basis of its own merit. If you try to propagate it on basis of Microsoft's demerit, you will face this question without fail: "Will open source products do everything that this paid software doesn't do?".
Saying things like "How Windows lost to Linux or OSS", "Why windows is crap", etc is not going to propel you upwards, it will only push you downwards.
